Bird brains are radically different from mammalian brains, but produce similar levels of intelligent thought. Bird brains might actually be superior since they are made of smaller, more densely-packed neurons, meaning a bird would be smarter than a mammal whose brain had the same volume. Hundreds of years from now, “humans” might have denser brains and smarter minds thanks to radical genetic engineering that takes inspiration from other organisms.

Using genetic engineering, scientists were able to transplant sperm from one male farm animal to a sterile male of the same species so that the recipient male produced the same sperm as the donor male. This could make it cheaper and easier to breed prized farm animals by using genetically inferior males as “surrogate fathers” for their offspring, and it could let us resurrect extinct species for which we have frozen sperm samples.

A recent experiment with an underwater server farm went well. Cooling costs were much lower because the capsule was immersed in cold seawater, and few of the servers failed because the atmospheric content in the capsule could be controlled better (a pure nitrogen atmosphere helped because oxygen corrodes computer circuits and cables). For this and other reasons, I think intelligent machines might live in the oceans.

Many common, manmade objects could be made more durable and longer-lasting, for relatively small up-front cost. However, this is rarely done since it goes against the interests of manufacturers, who want consumers to buy replacement goods often. Planned obsolescence is real and pervasive. It’s disturbing to think about how big a share of global economic activity is people buying replacements things that shouldn’t have needed to be thrown out.

“Center Barrel Replacement Plus” is a maintenance practice in which an F/A-18 fighter plane has the middle section of its fuselage cut out and replaced with a new section. The aircraft’s wings and landing gear are attached to the “center barrel,” so the joints there wear out faster than any other part of the plane. One of the improvements incorporated in the more advanced F/A-18 Super Hornet is a modular fuselage. This allows maintenance crews to replace center barrels with greater speed and ease.

Anyone familiar with the WWII European Theater will have heard about the feared “German 88mm,” which was the most effective antiaircraft and antitank shell of the War. It could punch through the armor of any Allied tank. I then remembered that postwar American tanks had 90mm cannons, which is only 2mm different from 88mm. It occurred to me: Did we copy the German 88mm cannon after seeing how effective it was in WWII? Kind of! When the War started, the U.S. was already using a 90mm cannon, but only as an antiaircraft weapon. The shell’s ballistics were almost the same as the German 88mm. Only after seeing how effective that type of weapon could be if mounted in a tank did we decide to start doing the same (we made this insight later than the Germans, so our 90mm tanks weren’t ready until 1945). After WWII ended, we realized that tank combat had changed forever, and that 90mm should be the new standard going forward.

President Trump listens as coronavirus response coordinator Deborah Birx speaks during a briefing at the White House.

Remember this White House briefing from March 31? The graph behind the podium showed that, with a lockdown, 100,000 – 240,000 Americans would still die of COVID-19. The X-axis was unlabeled, but since the figures in the graphs are shaped like humps, we can conclude that it pertained to the time period corresponding to the virus’ first wave. So in other words, on March 31, the White House said that the first wave of the pandemic would kill 100,000 – 240,000 Americans. The first wave has not ended, and as of today, the U.S. death toll is at least 180,000. Projections from other reliable sources I’ve found indicate that the second wave will start around mid-September, as the weather cools, and that the death toll at that point will be almost 200,000. So the first wave of the virus will end up killing a number of Americans that is nearer the high end of the March 31 projection.

The USS Yorktown was a U.S. aircraft carrier that sank during the pivotal Battle of Midway in 1942. After being bombed by Japanese planes, it started filling with water and leaning to one side. At 2:28 pm on June 4, all of its crew abandoned ship, convinced it would soon sink.

They were wrong. The damage was not fatal, and from the safety of another U.S. warship, they saw that the Yorktown was still afloat hours later. Fourteen hours after leaving, they started returning to the stricken carrier to fix it. They worked feverishly for the next 24 hours, and were making progress pumping water out of the ship, reducing its tilt. Unfortunately, a Japanese sub spotted them and torpedoed the carrier, this time destroying it for good. The sub also blew up another U.S. ship.

This makes me wonder what would have happened if the crew had never abandoned the Yorktown in the first place. That extra 14 hours of time might have enabled them to sufficiently repair and move the ship out of the area to prevent it from falling prey to the sub.

It costs $10.9 million to train a pilot how to fly an F-22 fighter, and $1.1 million to train one to fly a C-17 cargo plane. All the USAF’s costs for training pilots for its other types of planes are in between. Of course, that’s not the end of it. Those are only the costs of getting a new person UP TO the level of being able to fly their plane. Since people forget things, the pilots have to frequently undergo retraining and re-certification, which means more money spent each year (the RAND analysis doesn’t show those figures) as a continual expense. This means the cost savings of inventing computers that can fly warplanes as well as humans will be massive. There will also be no risk of pilots being shot down over enemy territory, captured, and used as political pawns.

Are aliens hibernating until the day the universe gets colder? If they are intelligent machines, then they would generate a lot of heat, and a colder environment would let them radiate that heat more efficiently, allowing them to do more computation. “[If such aliens hibernated until the universe’s temperature dropped from 3 Kelvin to less than 1 Kelvin] they could achieve up to 10^30 times more than if done today.”

Turing Award-winner John Hopcroft thinks machines will make human workers obsolete, and he points out that, just because humans have been able to climb up the skills ladder in the past faster than machines could automate old jobs, doesn’t mean we will be able to do that forever. Past trends don’t continue indefinitely, and there’s no reason why we couldn’t get into a situation where machines took over 1 million human jobs in a given year, but only 900,000 new jobs for humans were created during that same period. Hopcroft suggests dealing with this by spreading out the remaining jobs among more humans by finding ways to shorten the amount of time the average person works.

Elon Musk is still scared of AI. He thinks they could get smarter than humans in five years, and that things would get “unstable or weird” shortly after. I think his prediction is way too optimistic, and what might happen in five years is a machine passing the Turing Test, meaning it can carry on conversations with people and answer questions as well as a human. Things will get “weird” after that because many people dealing with such machines will mistakenly assume that they are “intelligent,” and perhaps even smarter than humans (e.g. – you’ll be able to ask a machine to do a complex math problem, and it will give you the solution right away). But the Turing Test machines and the autonomous cars we’ll have by the end of this decade will not actually be intelligent, self-aware, or capable of creative thought. Only at the surface level will they seem so. I doubt a true AI will be built earlier than midcentury.

Flooding has become a worse problem in New Orleans and some other coastal areas because of “land subsidence.” As humans pump aquifer water, oil, and natural gas out of the ground, all the little voids empty out, the dirt compacts, and the ground level sinks. This problem is not connected to global warming, and shows that some flooding is not due to rising sea levels or worsening storms.

Cosmic rays are responsible for the right-handed chirality of DNA. If the rays are omnipresent in the galaxy and have the same energetic properties everywhere, alien DNA should share our chirality.

DNA and RNA are also more structurally suited to their roles storing genetic information than any other type of biomolecule, so it’s likely that all but the most primitive types of aliens will use DNA and RNA.

Silicon-based, ORGANIC life forms are unlikely to exist.
‘Only a tiny fraction of the theoretical chemical space of silicon chemistry can be stable in water (Section 3.2.1). In fact, some of the commonly held views about the low diversity of silicon chemistry come directly from the instability of silicon chemistry in water. Silicon chemistry in water also requires substantially more energy to access than equivalent carbon chemistry (Section 3.3). For all of the above reasons, we argue in this subsection that silicon is unlikely to be a scaffold element or a common heteroatom element in water.’

In the 1970s, there was an ambitious project to compile a 6 million-page history of America from its founding to WWI into a document called the Library of American Civilization. It would have been in “ultrafiche” format, with each ultrafiche being 3″ x 5″ and containing up to 1,000 page images, shrunk from original size by a factor of 55 to 90. The idea was to distribute the document, along with ultrafiche readers, to every major library in America.

Once all the combustible material in the area was burned, they would drive to the next area and repeat.

A medical paper published last month in the Lancet claimed that the anti-malaria drug hydroxychloroquine actually increased the overall odds of dying among people who took it to treat COVID-19. People from many quarters quickly jumped on it as proof that President Trump’s advocacy of the drug was mistaken. However, the paper was recently retracted after nonpartisan scientists pointed out it didn’t include enough data supporting its conclusion.

The massive Ford car factory site at River Rogue, MI had a “car disassembly plant” from 1930-44. Hundreds of men worked there, systematically stripping parts off of Fords and other brands of cars, reusing or reselling what was still good, and melting down the rest to make metal for new Fords. I predicted this will return by the end of the 2030s thanks to cheap robots: “The same kinds of facilities will make inroads into the junk yard industry, as they would have all the right tooling to cheaply and rapidly disassemble old vehicles, test the parts for functionality, and shunt them to disposal or individual resale. (The days of hunting through junkyards by yourself for a car part you need will eventually end–it will all be on eBay. )”

The Philippines “Presidential Security Group” has the most interesting camouflage uniforms I’ve seen. As wacky as it looks, it actually adheres to the best principles of military camouflage (coarse pixelation, use of parallel and perpendicular lines and hard angles instead of wavy lines).

This video explains why exotic forms of communication, like using only smells, touch, or gravity waves, are impractical and grossly inferior to the forms of communication we use (speech, looking at writing, radio signals). Also, it makes the point that aliens could learn human languages by listening to our radio broadcasts and finding simple patterns, like the fact that the word “breakfast” is mentioned most often in the mornings, and is usually associated with words relating to food and hunger. They could learn our languages, at least to an elementary degree, without interacting with us.

This video provides a good overview of radar jamming. Radar is of course used to detect the locations of planes and ships. A radar station does this by sending out beams of radio waves, and then waiting to see if any of those waves bounce off a solid object and are reflected back to the station. The radar’s computer compiles any such echoes into a visual representation of the planes and ships, which looks like the familiar, circular computer screen image of little white dots against a black background. A human sits at a chair watching this screen. To jam a radar, you point a radio emitter of your own at the radar station and shoot powerful radio beams at it. The radar station’s receiver is overloaded, and the circular screen displays static, or goes 100% white. It’s conceptually the same as blinding a human by shining a very bright flashlight in his eyes.

The rise of AI will revolutionize warfare because it will let countries build arbitrarily large numbers of combat robots. The size of a country’s military will no longer be limited by the size of its human population. Conventional warfare will become as big a threat to humanity’s existence as nuclear war is now.
“We envision fleets of smaller, multi-mission vessels, operating with surface warfare leadership. People talk about a 355-ship Navy, how about a 35,000-ship Navy?,” Maj. Gen. David Coffman…[he] explained it as a “family of combatant craft, manned and unmanned, integrated in a distributed maritime operation.”

It will be interesting to see the prototype ship designs that result from this.
‘NOMARS will challenge the traditional naval architecture paradigm, designing a seaframe from the ground up with no provision, allowance, or expectation for humans at sea. By removing the human element from all ship design considerations, NOMARS will demonstrate significant advantages, to include size, cost (procurement, operations, and sustainment), at-sea reliability, survivability to sea-state, survivability to adversary actions (stealth considerations, resistance to tampering, etc.), and hydrodynamic efficiency (hull optimization without consideration for crew safety or comfort).’

The cost of solar power has dropped faster than any credible person predicted, even ten years ago. This supports my prediction that the 2020s will be the decade when better, cheaper solar panels and grid storage batteries will make solar power cost-competitive with standard forms of energy, even without government subsidies.
https://rameznaam.com/2020/05/14/solars-future-is-insanely-cheap-2020/

A big problem with solar and wind power is intermittency. To compensate for their sudden swings in electrical output over the course of the day, the people in charge of the electric grids have to throttle other power plants up and down. Natural gas power plants are best suited for this, but quickly dialing them up and down still greatly reduces their efficiency, releasing more CO2 into the atmosphere than they otherwise would. (We REALLY need to invent better batteries for grid energy storage.)

In this interview from two months ago, Bill Gates predicted that that the number of active COVID-19 cases would peak in every part of the U.S. by late April. He was pretty accurate, though a handful of states didn’t peak until early May, and Arizona has still not peaked. Gates went on to predict that a month would have to pass after those peaks for states to start safely lifting their lockdowns, meaning that we’d start seeing a lot of that around late May (now). Again, he was right.

-After that, distributing the vaccine to everyone will take months or years.
-By the end, the COVID-19 pandemic will have cost the world tens of trillions of dollars. (2019 global GDP was $85 trillion)
-The vaccine will probably become part of the standard vaccine schedule given to infants.

What color is your power armor?

My recent analysis of the combat exoskeletons from Edge of Tomorrow made me realize that there are at least three types of humanoid or animal-like mechanical fighting machines frequently depicted in science fiction, and I’ve decided to explore their feasibility. I think they can be grouped into these categories:

  1. Power armor / exoskeleton
  2. Mechwarrior (“Mech”)
  3. Jaeger / Zord

Power armor / exoskeleton

Defining characteristics:

  • Can only accommodate one person.
  • Provides some combination of enhanced strength, endurance, speed, or carrying capacity.
  • Best thought of as a “suit.”
  • If worn, the person’s overall size is not so big that they can’t fit through standard-sized doorways or into vehicles designed for un-armored people.
  • The suited person remains narrow enough to fit between trees and duck under branches in wooded areas.
  • Depicted in Edge of Tomorrow, the Fallout, Starcraft, and Halo video games

Problems and disadvantages:

  • Limited power supply (can’t fit a big battery into a relatively small machine and expect it to last long)
  • Could limit mobility and agility so much that you’re better off not wearing it.
  • Potentially dangerous to the wearer and to comrades who are not wearing their own, protective suits. Risk of serious accidents rises if your strength is amplified and you have lots of heavy, unyielding metal strapped to your body.

Feasibility:

  • Mildly feasible.
  • Light exoskeleton that increases load-carrying capacity of infantrymen, or lets them carry heavier weapons than otherwise possible (like .50 caliber machine guns) could be valuable and practical someday.
  • Heavy, fully enclosed exoskeleton for short duration, close-combat missions might also be practical.
  • Best use might be in noncombat logistic roles, like picking up and moving heavy cargo around bases.
  • Discussed at length in my blog entry about Edge of Tomorrow.

Mechwarrior (“Mech”)

Defining characteristics:

  • Can accommodate one or two people.
  • Can’t fit through standard-sized doorways or into other vehicles except large cargo planes and maybe large cargo helicopters.
  • Similar size and firepower as a tank or attack helicopter.
  • Should be thought of as a military vehicle and not as a suit.
  • Primarily or exclusively designed to fight using guns, missiles, and other ranged weapons. Usually ill-suited for hand-to-hand combat.
  • In theory, can traverse rougher terrain than wheeled/tracked vehicles thanks to its legs.
  • Depicted in Return of the Jedi, the Mechwarrior and Titanfall video games
The “spider tank” from the Ghost in the Shell anime movie is a more realistic type of mech since it has more than two legs and a low center of gravity.

Problems and disadvantages:

  • Having legs instead of wheels or caterpillar tracks would be problematic.
    • Legs would propel the vehicle slower than wheels or caterpillar treads. The ride would also be much bumpier, which would be exhausting and potentially disorienting for crewmen. Combat performance would suffer if the crewmen were dizzy and beat-up by the time they arrived at the battle site.
    • Mobility advantage over wheeled and tracked vehicles is questionable since mechs would have higher ground pressure–all of their weight would be concentrated on two feet, whereas traditional armored vehicles spread out their weight over 6-8 large wheels or two, long caterpillar tracks. This means a mech would have worse problems sinking into the mud and getting stuck.
    • Having a humanoid or animal-like layout (i.e. – legs for sure, and possibly arms as well) would increase a fighting vehicle’s surface-area-to-volume-ratio compared to a traditional wheeled or tracked vehicle with the same size and firepower. A mech would thus need to devote more of its mass to armor to achieve the same, all-around ballistic protection as a tank. Increasing the armor would necessitate deleting other things to save weight (e.g. – reduce fuel, ammo, or main weapon size/power).
    • The powertrain would need to be heavier and more complicated. A conventional tank like a T-72 essentially has a big truck engine that is transversely mounted and spins a shaft connected to one wheel on either side of the vehicle. It’s a simple and compact layout. A layout designed to move two, multi-jointed legs would be much more mechanically complex, requiring multiple motors and many spinning shafts, meaning more weight and more moving parts that can fail.
  • Its width would prevent it from going down alleys or between closely-spaced trees. Human enemies could run to constricted areas like that for cover. The mech’s big selling point–that it can go places where trucks and tanks can’t–is eroded thanks to the tree problem.
  • Its tallness would impose many problems.
    • Forested areas become even more impassable since branches can block mechs and/or obscure their crewman’s view of targets at ground level. Power lines, some road lights, and bridges/overpasses also turn into obstacles. The mechs definitely can’t be used for peacekeeping or domestic policing if they’re going to be constantly snapping power lines and cutting off electricity to whole neighborhoods. High ground pressure might also damage roads by leaving footprint indentations.
    • The taller and wider a mech is, the bigger of a target it becomes, and the easier it is for enemies to shoot it from longer ranges.
    • Mech would have high centers of gravity that would introduce the risk of tip-overs. Even if falling over didn’t destroy a mech, it could do enough damage and injury to the vehicle and crewman, respectively, to knock them out of the fight.
    • The torque from shooting heavy weapons mounted high on the mechwarrior would tip it over.
  • Accidental injury problem would be worse than in power armor / exoskeletons. For example, if a mech fell over by accident, it could crush friendly 20 infantrymen.
A “walking excavator” provides the design basis for the most practical type of combat mech

Feasibility:

  • Probably infeasible. There’s a reason why there are tens of thousands of advanced tanks in global military service, but not even one, basic mech.
  • It would be better to use aircraft and infantry to patrol and fight in areas where the terrain is too rough to bring in tanks and wheeled vehicles. Probably not worth it to build mechs just for specialty engagements in those places. Mechs might provide an advantage there, but would be inferior to traditional military vehicles in all other types of terrain. Not a flexible asset.
  • Building a useful mech is a much bigger technical challenge than making powered exoskeletons.
  • If we decided to build combat mechs anyway:
    • Designing them with four or more legs would make them safer, more stable, less likely to get stuck in the mud (ground pressure problem), and would offer a smoother ride than mechs with two legs. Problematically, a human pilot wouldn’t be able to intuitively control a machine that had more than two legs. Like in a car, the pilot would probably use a steering wheel and pedals to input direction and speed commands to the mech, and the mech’s computer would figure out exactly how to reposition the 4+ legs to achieve that. However, this disconnect between inputs and fine movements of the vehicle could lead to problems if the computer stepped on, say, a land mine, friendly infantryman, or an open sewer hole that the human pilot could see and wanted to avoid.
    • Making it as low to the ground as possible, with its volume distributed horizontally as opposed to vertically, would make it more stable and reduce its target profile.
    • Spider-like or beetle-like mech makes more sense than human-like mech.
    • The number of legs would present a tradeoff between vehicle stability and smoothness of ride vs. fuel efficiency and mechanical complexity/breakdown rate. Unsure what the optimum number of legs would be, but “two legs bad” for sure.
    • Would probably need built-in wheels for easy transport over roads and flatter ground. Remember, it won’t be climbing jagged hills or stepping over big logs in the forest all the time. This would also be easier on the crewmen.
    • The most practical design might resemble a “walking excavator,” but with armor and heavy weapons comparable to what is found on APCs. Couldn’t have the same firepower, speed, or protection as a main battle tank. (Videos showing walking excavators in action: 1) https://youtu.be/Hn1aZQFhC40 2) https://youtu.be/j87k71kOBis)
    • Would have a 360 degree rotating gun turret, like almost all armored vehicles. Wouldn’t need as big of a cannon since heavily-armored tanks wouldn’t be able to get into the rugged terrain areas where mechs would operate (20mm – 40mm cannon would be fine against other mechs, infantry, structures, and entrenched positions).
    • Might make sense to have heavy-lift helicopters transport mechs to their battle/patrol zones (mountain top, forest clearing, sand dune area).
    • A fully automated mech that lacked human crewmen wouldn’t suffer from many of the problems listed in this section, like disorientation and exhaustion from a bumpy ride. Small, unmanned turret would reduce center of gravity as well.

Jaeger / Zord

Defining characteristics:

  • Huge. At least 100 ft tall. Size and firepower are comparable to warships (modern destroyer or cruiser).
  • Strong enough to win fights with big groups of armored vehicles and planes attacking it at once.
  • Best thought of as a “one-man army.”
  • Can go anywhere since its feet are so big it can just step on and crush trees and walk up hills like they were steps. Can also wade through shallow bodies of water.
  • Has standoff weapons like missiles and cannons but is also designed for hand-to-hand combat and striking with oversize, handheld weapons like giant swords.
  • Depicted in Pacific Rim, several Godzilla movies, the Power Rangers TV show and movies.

Problems and disadvantages:

  • The “square-cube law,” along with limitations on the strength-to-weight ratios of physical materials, effectively prohibits the construction of machines this big that can also rapidly walk around and violently swing their arms (it also prohibits the existence of animals in the same size range).
  • Massive investment of money and resources into a single weapon that can only be in one place, at one time would probably be better spent on many smaller weapons (e.g. – tanks, fighter planes, mobile missile launchers) that can be spread out to patrol and fight enemies across large areas, and concentrated in one place when necessary to fight against a strong enemy.
  • Falls and tip-overs would be fatal to human pilots. Accidentally falling onto buildings or groups of friendly troops could kill hundreds of people at once.
  • Shares many of the same problems mech have, but to a worse degree.
  • They would be gigantic targets that enemies could see and shoot at from dozens of miles away, or bomb from high altitudes. They wouldn’t be able to hide themselves except in cities among skyscrapers, in canyons, or perhaps by diving into deep bodies of water. In every other environment, they would be impossible to camouflage.
  • Explored in my End of Evangelion review.

Feasibility:

  • Infeasible for many scientific and engineering reasons.
  • We would need Star Trek levels of technology (radically stronger and lighter materials, miniaturized fusion reactors, and cheap ways to build both) to make the sorts of Jaegers and Zords shown in the movies. With current technology we might be able to build Jaegers and Zords that were extremely slow, fragile, expensive, and of almost no military value. They would be missile- and gun platforms only, and would break themselves if they punched or kicked anything hard.
  • Even if the Star Trek technology existed, it’s doubtful anyone would make a Jaeger/Zord since it’s better to create a land force made up of many small, expendable units than to invest everything in one giant, all-important fighting machine. A single point of failure is really bad. A force made of many units is also more flexible since they can be spread out across a large area.

Additional thoughts on power armor / exoskeletons

  • The most realistic of the three types of fighting machines.
  • A minimalist exoskeleton with attachment points for big weapons like .50 cal machine guns, grenade launchers, and recoilless missile launchers would let infantry squads bring heavier weapons on patrols into rugged terrain areas. Squad members wearing the exoskeletons could fill some of the firepower niche that mechs are intended to fill.
  • Instead of all the troops wearing those exoskeletons with big weapons, it might be worn by every fifth or tenth man, specially trained for that equipment. Most of the troops would have normal weapons and would have no exoskeletons or lighter exoskeletons just designed to increase their load carrying capacity and to ease the physical strain of long marches.
  • Might work like this: Squad leader keeps the .50 cal exo-soldier in the back of the line unless needed. If so, he calls him up and deploys him carefully.
  • My thinking is guided by assumptions about existing science and tech. Exoskeletons would be totally plausible with Star Trek technology (e.g. – super light, super strong metal; flexible bulletproof body panels, personal fusion reactors).
  • Avatar final battle would actually be ideal scenario to use heavy weapon exo-soldiers. Forest environment blocked air support and wheeled vehicles (the tree cover would have also made it impractical to deploy mechs). Idea was to use helicopters to insert troops, win, and then recover them after a few hours, so no risk of batteries dying. Enemies were large, so abnormally large weapons needed.
  • Unclear if Edge of Tomorrow beach landing was well-suited to exo-soldiers. Mimics were very fast, but not actually that robust. Regular troops with normal weapons would have been better since they were faster and more agile. Also could have landed greater number of regular troops with same number of transport craft.

Interesting details about the V-22:
-“Many of the challenges in developing and operating the V-22 are the result of designing a fairly large platform to operate within the confines of US Marine Corps amphibious ships. This caused several compromises, such as a smaller proprotor diameter, which increases the download and reduces the hover efficiency, and a shorter wing, which reduces the amount of lift and range.”
-“These engineering lessons and the lack of shipboard size constraints enabled Bell to reduce the downwash from the rotors, design the rotors to tilt from horizontal to vertical without rotating the engines, and improve the reliability and availability of components. The V-22’s downwash, or high velocity air from the two tilting proprotors producing 22,680 kg of thrust to keep the aircraft aloft, can damage objects or injure people below. It also means the Osprey must burn more fuel to hover.”
-“In addition, the V-22 required a rear-ramp exit to avoid hot-engine exhaust blasting onto ship decks and grassy landing zones. As the V-280’s engines do not rotate, this solves the hot engine exhaust issue, which can start brush fires, and means troops can ingress and egress via side doors.”

For the first time on record, and probably for the first time since the era of Mao’s Mickey Mouse Economics, the Chinese economy shrank. The pandemic was the obvious cause.

Mapping the Global Future 2020

“The process of globalization, powerful as it is, could be substantially slowed or even stopped. Short of a major global conflict, which we regard as improbable, another large-scale development that we believe could stop globalization would be a pandemic…”

That is probably the most chillingly prescient passage from Mapping the Global Future, a report written 16 years ago by experts working for the U.S. National Intelligence Council, describing coming developments in geopolitics, culture, technology, and the economy out to 2020. With the year in question having arrived, I thought it was worthwhile to review the accuracy of it’s predictions, and overall, I was impressed. Mapping the Global Future correctly identified most of the megatrends that shaped the world from 2004-20, (though it was somewhat less accurate forecasting the degrees to which those factors would change things):

  • No significant expansion or strengthening of liberal democracy. From 2004-20, for every Myanmar there was a Turkey, and the number of “real” democracies across the world didn’t significantly change. Contrast this to the 15 years preceding the report’s publication, in which communism fell in Europe and Central Asia, along with many dictatorships in Latin America and Africa. The report’s authors correctly gauged that conditions were not ripe for another wave of international democratization.
  • Solid growth of global economy. The report failed to predict the Great Recession, but so did all other experts. Nevertheless, report’s estimate that the 2020 gross world product (GWP) would be 80% larger than it was in 2000 was very close to being right: it actually rose by 74% (adjusted for inflation).
  • Massive growth in China, and to a lesser extent, India. This was not the hardest prediction to make, though it should be noted that a minority of foreign policy experts in 2004 thought China might fall apart by 2020, probably thanks to political problems. I think the extent to which China’s growth (economic, military, technological, average living standards) ended up surpassing India’s would have surprised the authors.
  • Little or no weakening of Islamic extremism and terrorism. At this moment, there is a relative lull in the level of violence, but just three years ago, ISIS was at its peak, and nothing is stopping an “ISIS-level” resurgence of Islamic violence (Africa is likeliest to be the next hotbed). While the U.S. has dodged a sequel to 9/11, the total number of people killed worldwide by Muslim fanatics might actually be higher now than it was in 2004. The conditions that gave rise to Islamic terrorism in 2004 still exist in large parts of the world. Finally, the report made the frighteningly accurate predictions that al Qaeda would be replaced by new terrorist groups (ISIS and Boko Haram), and that the formation of an Islamic caliphate spanning multiple countries was even possible.
  • Very low likelihood of war between the great powers. Russia, China, and the U.S. didn’t even come close to fighting. A lot of ink has been spilled since 2004 about accidents–like U.S. and Russian planes shooting each other down over Syria–spiraling into all-out war, but I think cooler heads would have prevailed.
  • Weakening of U.S. global supremacy. The report correctly predicted that the U.S. would still be the world’s strongest country overall in 2020, but the gap between it and its nearest competitors–chiefly China–would be narrower. It was also right to forecast the weakening of the U.S.-led international banking and trade system.
  • Backlash against globalization and concomitant rise of populism and nationalism. From the election of Donald Trump, to Brexit, to the breakdown of the Doha Free Trade talks and the Trans-Pacific Partnership, to near-constant angst over the erosion of the middle class due to outsourcing and illegal immigrant laborers, to the rise of chauvinist strongmen across the world, we see clear proof of these trends. The struggle between liberal globalists and conservative nationalists became THE cultural and political fissure during the 2004-20 time frame.
  • Major impact of internet on culture, self-identity, business, and other aspects of life. As the report predicted, the expansion of the internet to most of the human race has empower global movements like the Arab Spring, fragmented and upended the news media landscape, and facilitated the rise of more complex human identities and group loyalties that transcend national borders, making national governance and consensus-forming harder.
  • World vulnerability to pandemic. This isn’t explored in great detail, but the report makes it clear that the threat of a pandemic bad enough to halt globalization is real.

Of course, the report also had a few failed predictions and omissions, which are important to mention, but in my opinion, outweighed by what the report got right:

  • Didn’t foresee the Great Recession. I noted this before, and also how it had little effect on the report’s accuracy forecasting 2000-2020 global wealth growth. The report’s authors were also in good company, since no expert in 2004 predicted the Great Recession.
  • Didn’t foresee fracking. While the report doesn’t predict anything as calamitous as the world running out of oil by 2020, it says that oil prices could be significantly higher than they were in 2004 due to tighter supplies, leading to the usual fare of anxieties, political problems, and small-scale wars. Had fracking not been invented, this could well have been the case. Fracking has revolutionized the global energy landscape by boosting oil and natural gas supplies well beyond what almost all energy experts thought possible in 2004. More than anything, this failure should highlight the perils of trying to predict the future of the energy markets.
  • Didn’t foresee Venezuela’s near-implosion (could it still happen?). To be fair, Venezuela’s economy collapsed because their socialist government badly managed its oil industry after nationalizing it and because fracking then caused a sharp drop in world oil prices. The report’s experts couldn’t have foreseen how bad the mismanagement would get, and as noted, they also didn’t predict the rise of fracking.
  • Thought North Korea would “come to a head.” It’s unclear what the report’s authors were envisioning here (North Korea democratization? North Korea chaotic implosion? One Korea–possibly with the help of a superpower ally–annexing the other?), other than the status quo of a divided Korean peninsula with a hostile dictatorship in the North ending by 2020. That didn’t happen, and it’s crucial to remember that there’s a clear and now long-running pattern of “experts” making wrong predictions about this. (https://www.theatlantic.com/international/archive/2012/08/the-long-history-of-wrongly-predicting-north-koreas-collapse/260769/) It raises the possibility that North Korea could continue to endure for much longer than we expect, in spite of the reports of how brittle and strange the regime is and how desperate its citizens are.
  • Thought Taiwan would “come to a head.” The authors surely meant either a successful Taiwanese declaration of independence or annexation to China (probably by force). This also didn’t happen, and can also be added to the long list of wrong predictions about this issue.
  • Russia predictions were not great, not terrible. While the report’s authors correctly predicted that corruption, lack of foreign investment, population shrinkage, conflicts with its neighbors would leave Russia “stuck in neutral” in terms of absolute power and declining in terms of relative global stature, they didn’t predict how badly relations would deteriorate with the West, and foresaw Central Asia as Russia’s likeliest battleground when in fact it was Ukraine and the Caucuses. My guess is that they underestimated how skillful of a leader Putin would turn out to be, and also underestimated the Russians’ resolve to not let any more of their satellite states slip away to the Western camp.
  • Overestimated the risks of bioterrorism and nuclear terrorism. Contrary to the report’s fears, no terrorists have used, or to our knowledge obtained, biological or nuclear weapons since 2004. Overestimating the threat is understandable given the contemporaneous problem of loose Russian nuclear weapons and widespread fear of and misinformation about bioterrorism following the 2001 Anthrax Attacks. Russia’s recovery from the chaotic 1990s allowed them to secure all of their nuclear weapons, and biological weapons are actually much harder to create and successfully use than popular fiction and biased “experts” who got most of the attention around 2004 led the public to believe. (Note: Unfortunately, I think weaponized COVID-19 could make bioterrorism much likelier)

Thinking about what the expert authors of Mapping the Global Future got right and wrong leads me to following general conclusions about the course of world events, and about making predictions:

  • The status quo is strong. Slow, plodding megatrends and entrenched systems are very resistant to change, regardless of how outdated, suboptimal, or undesirable they may be. The fact that hand-wringing and doomsaying about issues like the divided Korean peninsula, contested status of Taiwan, unsustainable European welfare states, American global primacy, and nation-state model has been going on for decades without resolution should give us pause whenever we hear someone predict a shift in some paradigm. The “inevitability” of another American Civil War is a good example. The stodgy status quo is probably stronger and more resilient to shocks than you think, can ruthlessly destroy upstarts, and might be able to use little reforms to muddle its way through some problem that was widely believed to be unsolvable and fatal.
  • Some dictatorships are smart. Though the report was upbeat about China’s prospects, if anything, it underestimated how strong the country and its regime would become by 2020. China has of course averted collapse, and its communist government has skillfully suppressed democracy and ethnic minority discontent. In short, the dictatorship proved smarter and more competent than even most experts thought in 2004. The use of technology for mass surveillance will entrench it even more in the future. The report’s authors would also have been surprised at how nimble and strong of a leader Putin proved to be, and how well he’s played his country’s diminished hand on the world stage.
  • Not everyone is ready for democracy. The report correctly recognized that conditions were not right for significant expansions of liberal democracy from 2004-20. The disappointing results of the democratization experiments the U.S. ran in Afghanistan and Iraq, the failure of the Arab Spring, and the rise–with majority voter support–of populist strongmen across the world have been valuable, if painful, reminders that not every group of people is ready for or wants liberal democracy. Growing political dysfunction in the U.S. is also damaging the brand.
  • Rational actors are in charge and they suck the fun out of everything. The hard truth is that every major country, including the U.S., China, Russia, and even North Korea, is led by a rational actor–or, more accurately, by groups of people who cancel out each other’s worst ideas so that the resulting consensus decisions are adequately rational and informed. They all have an accurate grasp of the world and of their own interests, and base their key decisions on cost-benefit calculations, which is why North Korea doesn’t invade the South, China doesn’t invade Taiwan, the U.S. and Russia don’t start WWIII, etc.
  • Expert views are good, and usually better than non-experts, but never perfect. As I wrote earlier, I was impressed with the overall accuracy of the report’s predictions, and think the things they got right in aggregate outweigh the things they got wrong. The report’s accuracy probably owes mostly to the fact that it solicited views from “25 leading outside experts from a wide variety of disciplines and backgrounds to engage in a broad-gauged discussion with Intelligence Community analysts.” In other words, experts were invited to make predictions about things in their areas of expertise, which is Rule #1 in my Rules for Good Futurism.

In conclusion, I enjoyed this report and think the authors used a sound methodology for making future predictions. As a result, I’m planning to write a blog analysis of the latest sequel, the DNI’s 2017 Global trends: Paradox of progress, which predicts world events out to 2035.

If you’re interested in learning more about the 2020 report, read my notes on it below and key quotes I copied (which I’ve organized by country and subject), or read the report in full.

The U.S.

“The United States, too, will see its relative power position eroded, though it will remain in 2020 the most important single country across all the dimensions of power.” Yes, but an easy prediction to make.

“While no single country looks within striking distance of rivaling US military power by 2020…” Right.

“US dependence on foreign oil supplies also makes it more vulnerable as the competition for secure access grows and the risks of supply side disruptions increase.” Missed fracking! Also mentioned this in a non-U.S. section: “Thus sharper demand-driven competition for resources, perhaps accompanied by a major disruption of oil supplies, is among the key uncertainties.”

East and South Asia.

Right about rapid growth in China and India. Report correctly predicted that China would grow faster than India from 2005-20. Size of that gap might have surprised them. Not a good idea to constantly mention “China and India” together.

Predictions about huge growth in China’s middle class, overall purchasing power, and standards of living (like car ownership levels and frequency of overseas travel) were right.

“Meanwhile, the crisis over North Korea is likely to come to a head sometime over the next 15 years.” Another in a long history of failed predictions about its collapse.

“The possession of chemical, biological, and/or nuclear weapons by Iran and North Korea and the possible acquisition of such weapons by others by 2020 also increase the potential cost of any military action by the US against them or their allies.” North Korea did first nuclear test in October 2006. Iran has been dissuaded thanks to hardball diplomacy and direct intervention (nuclear computer virus, assassinations of leading people)–for now.

“By 2020, globalization could be equated in the popular mind with a rising Asia, replacing its current association with Americanization.” Accurate. The U.S. is retrenching under Trump, but China’s global reach is still expanding through its Belt and Road Initiative (created in 2013) and other large investments in Africa and almost everywhere else.

“What Would An Asian Face on Globalization Look Like?
…Asian finance ministers have considered establishing an Asian monetary fund that would operate along different lines from IMF, attaching fewer strings on currency swaps and giving Asian decision-makers more leeway from the “Washington macro-economic consensus.””
China founded the Asian Infrastructure Investment Bank in 2015 as a direct rival to the IMF.
…An expanded Asian-centric cultural identity may be the most profound effect of a rising Asia. Asians have already begun to reduce the percentage of students who travel to Europe and North America with Japan and—most striking—China becoming educational magnets. A new, more Asian cultural identity is likely to be rapidly packaged and distributed as incomes rise and communications networks spread. Korean pop singers are already the rage in Japan, Japanese anime have many fans in China, and Chinese kung-fu movies and Bollywood song-and-dance epics are viewed throughout Asia. Even Hollywood has begun to reflect these Asian influences—an effect that is likely to accelerate through 2020.” U.S. pop culture still reigns supreme globally, and in spite of spending huge amounts of money, China has had little success making films, music, or other cultural products that outsiders like. However, China’s influence has grown anyway, and disturbing examples include the recent, high-profile instances of China pressuring U.S. sports and entertainment companies to self-censor.

“The regional experts felt that the possibility of major inter-state conflict remains higher in Asia than in other regions. In their view, the Korean Peninsula and Taiwan Strait crises are likely to come to a head by 2020, risking conflict with global repercussions. At the
same time, violence within Southeast Asian states—in the form of separatist insurgencies and terrorism—could intensify. China also could face sustained armed unrest from separatist movements along its western borders.”
The crises did not come to a head! Important to pay attention to these failed predictions. Maybe they’ll continue to fail forever, and there will not be violent resolutions to Korea and Taiwan (expert predictions about inevitable U.S.-Soviet war were also wrong). The insurgency in Xinjiang did worsen, but China crushed it with martial law and reeducation camps. Russians also crushed Chechen insurgency. Sad testimony about the effectiveness of government repression? Even more effective in the future thanks to mass surveillance tech?

“Asia is particularly important as an engine for change over the next 15 years…Both the Korea and Taiwan issues are likely to come to a head, and how they are dealt with will be important factors shaping future US-Asia ties as well as the US role in the region…Japan’s position in the region is also likely to be transformed as it faces the challenge of a more independent security role.” None of that happened. Japan never transitioned from its isolationist, defensive posture to an international role that was more active and independent of the U.S. Japan’s alliance with the U.S. remains its most important and defining interstate relationship.

“China and India, which lack adequate domestic energy resources, will have to ensure continued access to outside suppliers; thus, the need for energy will be a major factor in shaping their foreign and defense policies, including expanding naval power.
…Beijing’s growing energy requirements are likely to prompt China to increase its activist role in the world—in the Middle East, Africa, Latin America, and Eurasia. In trying to maximize and diversify its energy supplies, China worries about being vulnerable to pressure from the United States which Chinese officials see as having an aggressive energy policy that can be used against Beijing.”
Correct. A big reason for the Belt and Road Initiative is to secure oil and gas supply lines from the Middle East and Central Asia to China. China also launched its first aircraft carrier in 2012 and has sharply expanded and improved its navy since then. While some worry the navy is being built up to take over Taiwan, its equally important purpose will be to protect the oil shipping lanes that run from the Persian Gulf to China’s coast.

China’s sex ratio imbalance has not caused major problems as the report suggested might happen. Again, China proved more stable and its government more able to deal with problems than outsiders worried.

Report’s hopes of China taking steps towards democracy were dashed. Instead, Chinese government has effectively placated its populace with economic growth, security, and propagandization. China’s success has put forth what might be a viable political / economic / social alternative to Western liberal democracy, and I believe the former’s appeal is one reason why global democratization has slowed. Dictators see there is another way.

The report calculates that, in spite of China’s rapid economic growth, it will take decades before it gets rich enough to emerge from the ranks of “middle income” countries: In 2050, per capita Chinese GDP will only equal per capita GDP in Western countries in 2004. This will probably prove true, but remember that life wasn’t bad for us Westerners in 2004 (I clearly remember it!). Raising the average standard of living for people in a country of 1.4 billion to 2004 American standards will be a monumental accomplishment. Also note that this economic forecast for 2050 is in line with my own prediction about China in the 2060s: “China will effectively close the technological, military, and standard of living gaps with other developed countries. Aside from the unpleasantness of being a more crowded place, life in China won’t be worse overall than life in Japan or the average European country.”

Former USSR

“The so-called “third wave” of democratization may be partially reversed by 2020—particularly among the states of the former Soviet Union and in Southeast Asia, some of which never really embraced democracy.” It happened. The Baltic states remain firmly democratic, Ukraine is a dysfunctional democracy where life is bad for most people, and all the others are undemocratic. Also, in SE Asia, Thailand democracy failed but Myanmar’s blossomed. No overall trend.

Correctly predicted that Russia would be stuck in neutral thanks to demographic decline, corruption, lack of foreign investment, and problems with its neighbors. However, incorrectly predicted that the conflicts would be with its Central Asian neighbors and about radical Islam, when in fact Russia fought with Ukraine and Georgia over geopolitics. (Not the only set of experts from that era who worried about Central Asian stability. Were they all fundamentally wrong, or has the problem just been delayed thanks to luck or some other temporary factor?) Russia’s relations with West got much worse than the report predicted thanks to the latter not tolerating the aggression. The report seems to have underestimated how fast Russia would recover from the torpor of the 90s, and its determination to not let more satellite states slip away to the West.

“In the view of the experts, Central Asian states are weak, with considerable potential for religious and ethnic conflict over the next 15 years. Religious and ethnic movements could have a destabilizing impact across the region.” Hasn’t happened…yet. Broader trend I’m seeing is underestimation of how powerful and competent secular dictatorships are at stamping out dissent. Look at failure of Arab Spring, particularly how it was crushed in Bahrain, and at how the military restored the status quo ante in Egypt. Also note the failure of the Iranian uprisings.

“Eurasia, especially Central Asia and the Caucasus, probably will be an area of growing concern, with its large number of potentially failing states, radicalism in the form of Islamic extremism, and importance as a supplier or conveyor belt for energy supplies to both West and East. The trajectories of these Eurasian states will be affected by external powers such as Russia, Europe, China, India and the United States, which may be able to act as stabilizers. Russia is likely to be particularly active in trying to prevent spillover, even though it has enormous internal problems on its own plate. Farther to the West, Ukraine, Belarus, and Moldova could offset their vulnerabilities as relatively new states by closer association with Europe and the EU.”

“If Russia fails to diversify its economy, it could well experience the petro-state phenomenon of unbalanced economic development, huge income inequality, capital flight, and increased social problems.” It happened. Russians have rallied around Putin, however, and have endured the effects of Western sanctions admirably. Part of this owes to the effectiveness of Russian government propaganda at convincing Russians to suffer for the Putin’s causes. Sounds like the report underestimated him in 2004.

Europe

“The EU, rather than NATO, will increasingly become the primary institution for Europe, and the role which Europeans shape for themselves on the world stage is most likely to be projected through it.” Right!

The report’s skepticism of E.U. army being created by 2020 was justified. Europeans still have serious problems with military cooperation.

“Over the next 15 years, West European economies will need to find several million workers to fill positions vacated by retiring workers. Either European countries adapt their work forces, reform their social welfare, education, and tax systems, and accommodate growing immigrant populations (chiefly from Muslim countries) or they face a period of protracted economic stasis that could threaten the huge successes made in creating a more United Europe.” They didn’t solve the problem, have protracted economic stasis, and have sharply slowed down the creation of a more United Europe.

“The experts felt that the current welfare state is unsustainable and the lack of any economic revitalization could lead to the splintering or, at worst, disintegration of the European Union, undermining its ambitions to play a heavyweight international role.” Brexit!

Latin America

“Populist themes are likely to emerge as a potent political and social force, especially as globalization risks aggravating social divisions along economic and ethnic lines. In parts of Latin America particularly, the failure of elites to adapt to the evolving demands of free markets and democracy probably will fuel a revival in populism and drive indigenous movements, which so far have sought change through democratic means, to consider more drastic means for seeking what they consider their “fair share” of political power and wealth.” Definitely happened.

Report’s short section on Latin America failed to predict Venezuela’s near-implosion.

Muslim world and Islam

“In particular, political Islam will have a significant global impact leading to 2020, rallying disparate ethnic and national groups and perhaps even creating an authority that transcends national boundaries.” This is an eerily accurate description of ISIS. Since the group was mostly destroyed, the overall threat posed by political Islam at this moment is lower today than it was in 2004, though its unclear if conditions will hold.

“The key factors that spawned international terrorism show no signs of abating over the next 15 years. Facilitated by global communications, the revival of Muslim identity will create a framework for the spread of radical Islamic ideology inside and outside the Middle East, including Southeast Asia, Central Asia and Western Europe, where religious identity has traditionally not been as strong.” The problem has stayed overwhelmingly confined to the Middle East and South Asia. Islamic terrorists have staged high-profile attacks in Europe, but the resulting deaths were dwarfed by the number killed in the Middle East and South Asia.

“Democratic progress could gain ground in key Middle Eastern countries, which thus far have been excluded from the process by repressive regimes. Success in establishing a working democracy in Iraq and Afghanistan—and democratic consolidation in Indonesia—would set an example for other Muslim and Arab states, creating pressures for change.” No real success. Iraq and Afghanistan are highly corrupt democracies that would collapse without direct U.S. military support. Tunisia became democratic, but I have doubts about its long-term survival.

“Reports of growing investment by many Middle Eastern governments in developing high-speed information infrastructures, although they are not yet widely available to the population nor well-connected to the larger world, show obvious potential for the spread of democratic—and undemocratic—ideas.” This happened. The Arab Spring was the “social media revolution,” and ISIS spread its crazed ideas, snuff videos, and terrorist training materials via the internet.

“Most of the regions that will experience gains in religious “activists” also have youth bulges, which experts have correlated with high numbers of radical adherents, including Muslim extremists.

Youth bulges are expected to be especially acute in most Middle Eastern and West African countries until at least 2005-2010, and the effects will linger long after.

In the Middle East, radical Islam’s increasing hold reflects the political and economic alienation of many young Muslims from their unresponsive and unrepresentative governments and related failure of many predominantly Muslim states to reap significant economic gains from globalization.

The spread of radical Islam will have a significant global impact leading to 2020, rallying disparate ethnic and national groups and perhaps even creating an authority that transcends national boundaries. Part of the appeal of radical Islam involves its call for a return by Muslims to earlier roots when Islamic civilization was at the forefront of global change. The collective feelings of alienation and estrangement which radical Islam draws upon are unlikely to dissipate until the Muslim world again appears to be more fully integrated into the world economy.”

The report contains a hypothetical 2020 letter between Muslim fanatics discussing the recent rise of an Islamic caliphate in the Sunni regions of Iraq, and its war against Shi’ites and U.S. military forces. The fictitious letter also says the conflict spurred a million Middle Eastern refugees to flee to the Western world. This is a frighteningly accurate description of actual events in the Middle East and Europe during the 2010s.

“We expect that by 2020 al-Qa’ida will be superceded by similarly inspired Islamic extremist groups, and there is a substantial risk that broad Islamic movements akin to al-Qa’ida will merge with local separatist movements.” Excellent prediction. ISIS and Boko Haram meet the description.

Global terrorism and organized crime

“Strong terrorist interest in acquiring chemical, biological, radiological and nuclear weapons increases the risk of a major terrorist attack involving WMD. Our greatest
concern is that terrorists might acquire biological agents or, less likely, a nuclear device, either of which could cause mass casualties. Bioterrorism appears particularly suited to the smaller, better-informed groups. We also expect that terrorists will attempt cyber attacks to disrupt critical information networks and, even more likely, to cause physical damage to information systems.”
Terrorists have evidently made no progress on this, though the coronavirus pandemic’s damage will surely inspire terrorists to try harder.

“Over the next 10 to 20 years there is a risk that advances in biotechnology will augment not only defensive measures but also offensive biological warfare (BW) agent development and allow the creation of advanced biological agents designed to target specific systems—human, animal, or crop.” No evidence it happened, though the chaos caused by coronavirus could inspire terrorist groups and crazed individuals to focus on BW. It is possible that Russia, China and other states have used new technology to secretly create deadlier bioweapons. Such weapons programs remain beyond the means of terrorists, but could be supported and concealed by a competent government.

Thankfully, terrorists never got WMDs as the report feared. However, they still wreaked enormous havoc with conventional weapons and tactics–terrorists have killed about 200,000 people since 2004.

“If the growing problem of abject poverty and bad governance in troubled states in Sub-Saharan Africa, Eurasia, the Middle East, and Latin America persists, these areas will become more fertile grounds for terrorism, organized crime, and pandemic disease. Forced migration also is likely to be an important dimension of any downward spiral. The international community is likely to face choices about whether, how, and at what cost to intervene.” Yes, this happened. Muslim fundamentalism like Boko Haram in Africa, Mexican cartels worse than ever, refugee waves going to the U.S. and Europe.

“While vehicle-borne improvised explosive devices will remain popular as asymmetric weapons, terrorists are likely to move up the technology ladder to employ advanced explosives and unmanned aerial vehicles.” Terrorists have tried many times to kill people with UAVs, but been unsuccessful. Our luck won’t hold forever. In 2018, a drone was also used in an attempted assassination of Venezuelan president Maduro.

“We expect that terrorists also will try to acquire and develop the capabilities to conduct cyber attacks to cause physical damage to computer systems and to disrupt critical information networks.” Many small-scale attacks have happened, but we’re still waiting for The Big One. The ability for computer hackers to do things like cause nuclear meltdowns or disable national electric grids has been exaggerated.

“A key cyber battlefield of the future will be the information on computer systems themselves, which is far more valuable and vulnerable than physical systems. New technologies on the horizon provide capabilities for accessing data, either through wireless intercept, intrusion into Internet-connected systems, or through direct access by insiders.” This definitely happened. Since 2004, there have been too many big hacking incidents, in which troves of sensitive data and electronic assets were stolen. Also remember the high-profile data dumps on Wikileaks, including those courtesy of Edward Snowden.

“Organized crime is likely to thrive in resource-rich states undergoing significant political and economic transformation, such as India, China, Russia, Nigeria, and Brazil as well as Cuba, if it sees the end of its one-party system.” If Boko Haram is considered a mafia, then it did indeed get quite bad in Nigeria. Didn’t happen in the others though. Brazil is about as bad as ever. Report missed Mexico becoming a global center of organized crime. Cartel activity and the national murder rate shot up a few years after the report was published.

Globalization, nationalism and populism

“Some aspects of globalization—such as the growing global interconnectedness stemming from the information technology (IT) revolution— almost certainly will be irreversible. Yet it is also possible, although unlikely, that the process of globalization could be slowed or even stopped, just as the era of globalization in the late 19th and early 20th centuries was reversed by catastrophic war and global depression.” Globalization has definitely slowed. Consider Trump’s election, Brexit, growing resistance among Europeans to strengthening the E.U., the death of free trade deals like Doha, growing isolation and hostility of Russia.

“The transition will not be painless and will hit the middle classes of the developed world in particular, bringing more rapid job turnover and requiring professional retooling. Outsourcing on a large scale would strengthen the antiglobalization movement. Where these pressures lead will depend on how political leaders respond, how flexible labor markets become, and whether overall economic growth is sufficiently robust to absorb a growing number of displaced workers.” Yes, this is now a major political issue throughout the world. It’s unclear if the U.S. has permanently changed course or if Trump’s election just hit the Pause button on the U.S. outsourcing more jobs and importing more immigrant labor.

“Currently, about two-thirds of the world’s population live in countries that are connected to the global economy. Even by 2020, however, the benefits of globalization won’t be global. Over the next 15 years, gaps will widen between those countries benefiting from globalization—economically, technologically, and socially—and those underdeveloped nations or pockets within nations that are left behind. Indeed, we see the next 15 years as a period in which the perceptions of the contradictions and uncertainties of a globalized world come even more to the fore than is the case today.” Yes. Note the rise of populist, nationalist political parties and talking heads, and the new, near-constant focus on “inequality” in the press.

“Populist themes are likely to emerge as a potent political and social force, especially as globalization risks aggravating social divisions along economic and ethnic lines. In parts of Latin America particularly, the failure of elites to adapt to the evolving demands of free markets and democracy probably will fuel a revival in populism and drive indigenous movements, which so far have sought change through democratic means, to consider more drastic means for seeking what they consider their “fair share” of political power and wealth.” Definitely happened.

“What Could Derail Globalization?
The process of globalization, powerful as it is, could be substantially slowed or even stopped. Short of a major global conflict, which we regard as improbable, another large-scale development that we believe could stop globalization would be a pandemic…”

World economy

The report gives figures for “GNP,” but the metric is now known as “GNI.”

“Barring such a turn of events, the world economy is likely to continue growing impressively: by 2020, it is projected to be about 80 percent larger than it was in 2000, and average per capita income will be roughly 50 percent higher. Of course, there will be cyclical ups and downs and periodic financial or other crises, but this basic growth trajectory has powerful momentum behind it.” Missed the 2008 Great Recession, but then again, so did everybody. Regardless, the estimate was basically right. 2000 Gross world product (GWP) was $50 trillion while 2019 GWP was $87 trillion, meaning it grew 74% (note: figures are adjusted for inflation). The extra 6% growth we failed to achieve might owe to the Great Recession.

Technology

“The Internet in particular will spur the creation of even more global movements, which may emerge as a robust force in international affairs.” The Arab Spring was driven by young people with cell phones and social media. More generally, social media empowers people to organize and petition about all kinds of things, big and small, and to effectively pressure powerful people to do things.

“Moreover, future technology trends will be marked not only by accelerating
advancements in individual technologies but also by a force-multiplying convergence of the technologies—information, biological, materials, and nanotechnologies—that have the potential to revolutionize all dimensions of life. Materials enabled with nanotechnology’s sensors and facilitated by information technology will produce myriad devices that will enhance health and alter business practices and models. Such materials will provide new
knowledge about environment, improve security, and reduce privacy. Such interactions of these technology trends—coupled with agile manufacturing methods and equipment as well as energy, water, and transportation technologies—will help China’s and India’s prospects for joining the “First World.” Both countries are investing in basic research in these fields and are well placed to be leaders in a number of key fields. Europe risks slipping behind Asia in creating some of these technologies. The United States is still in a position to retain its overall lead, although it must increasingly compete with Asia and may lose significant ground in some sectors.”
What are “nanotechnology’s sensors”? Can’t really assess the prediction without knowing what that means. The smartphone revolution happened after this was written, and the devices contain many sensors that “have nanotechnology.” Neither China nor India are in the First World yet, but the former has made major strides improving its technology and even taking the lead in some niches.

“New technology applications will foster dramatic improvements in human knowledge and individual well-being. Such benefits include medical breakthroughs that begin to cure or mitigate some common diseases and stretch lifespans, applications that improve food and potable water production, and expansion of wireless communications and language translation technologies that will facilitate transnational business, commercial, and even social and political relationships.” The predicted computer-related advances happened, but progress in medical technology has been disappointing. Over the last 16 years, we’ve discovered that biology is messier, more complex, and less amenable to manipulation than software.

“The media explosion cuts both ways: on the one hand, it makes it potentially harder to build a consensus because the media tends to magnify differences; on the other hand, the media can also facilitate discussions and consensus-building.” The first point has outweighed the other, and misinformation, disagreement, and social fragmentation have probably never been worse. The authors couldn’t have known.

“Growing connectivity also will be accompanied by the proliferation of transnational virtual communities of interest, a trend which may complicate the ability of state and global institutions to generate internal consensus and enforce decisions and could even challenge their authority and legitimacy. Groups based on common religious, cultural, ethnic or other affiliations may be torn between their national loyalties and other identities. The potential is considerable for such groups to drive national and even global political decisionmaking on a wide range of issues normally the purview of governments.” Accurate. It has made people more tribal and fragmented.

Misc.

“The likelihood of great power conflict escalating into total war in the next 15 years is lower than at any time in the past century, unlike during previous centuries when local conflicts sparked world wars.” Quite true. I think it will get slightly higher over the next 15 as China closes some of the military power gap with the U.S.

“Countries without nuclear weapons—especially in the Middle East and Northeast Asia—might decide to seek them as it becomes clear that their neighbors and regional rivals are doing so.” There have been no concrete steps in that direction. The U.S. has successfully assured Japan and South Korea they are under its nuclear umbrella, so they haven’t started their own nuclear programs in response to North Korea getting the bomb. Also, since Iran has been dissuaded/blocked from building nukes (this counter-effort was probably more successful than the report authors would have predicted), its neighbors haven’t tried building their own.

“Both North Korea and Iran probably will have an ICBM capability well before 2020” North Korea does; Iran does not.

“By 2020, China and Nigeria will have some of the largest Christian communities in the world, a shift that will reshape the traditionally Western-based Christian institutions, giving them more of an African or Asian or, more broadly, a developing world face.” I don’t think this happened.

“Over the next 15 years, democratic reform will remain slow and imperfect in many countries due to a host of social and economic problems, but it is highly unlikely that democracy will be challenged as the norm in Africa.” Was right.

“We foresee a more pervasive sense of insecurity, which may be as much based on psychological perceptions as physical threats, by 2020. The psychological aspects, which we have addressed earlier in this paper, include concerns over job security as well as fears revolving around migration among both host populations and migrants.” I wholeheartedly agree that a large share of today’s popular anxiety is psychological and not tangible in nature. Threats are commonly being exaggerated and even manufactured to keep average people fearful, tragically distracting them from the fact that this is the best time to be alive in human history for most types of people. The cause is a toxic nexus between the darker aspects of human nature and the profit-driven incentives of news media outlets.

Review: “Edge of Tomorrow”

Plot:

In 2015, hostile aliens that humans call “Mimics” invade Germany and conquer most of Europe within five years. Human populations and military forces are pushed to the edges of the continent, and in mid-2020, a multinational army that has massed in Britain stages an amphibious invasion across the English Channel to retake the lost territory. The infantrymen wear powered combat exoskeletons that they call “Jackets,” and which give them super-strength and let them carry heavy weapons. Tom Cruise plays an American officer who is part of the first wave of the invasion.

The operation is a disaster: thousands of mimics are secretly entrenched in and around the French beach where the humans land, and the human soldiers’ advanced technology doesn’t save them from annihilation. Tom Cruise survives only a few minutes of combat before he detonates a bomb at suicidally close range to kill a mimic that is attacking him. That mimic is unusually large and is colored differently from all the others, the explosive blast tears it apart, and Tom Cruise is sprayed with its blood, which enters his body through his mouth, eyes, and open wounds also caused by the explosion. Seconds later, he dies of his injuries, but then awakens roughly 24 hours earlier, with his injuries healed and his memories of that horrible day intact.

No one else is aware of the time reset, and people who Tom Cruise saw die on the beach are alive again at the base, unhurt and clueless. When Tom Cruise tells his commander about what happened, he is dismissed as crazy, and is forced to participate in the amphibious invasion again. Events replay as calamitously as the first time, a mimic again kills Tom Cruise, and he wakes again, 24 hours earlier, this time with memories of TWO beach invasions that he fought in.

This sequence of events repeats itself several times without Tom Cruise understanding why, and with him experimenting with different tactics during each cycle. On one of the days, he meets a soldier played by Emily Blunt, and she explains the source of the time reset ability.

A hologram of the mimic Omega. This shows its form more clearly than the actual shots of it in the film.

The mimics consist of three species: 1) Drones, 2) Alphas, and 3) the Omega. The drones are expendable foot soldiers and are by far the most common type of mimic. The alphas are the battlefield commanders and look like larger, blue versions of drones. There is one alpha for every 6.8 million drones. The Omega is an enormous, stationary life form that kind of looks like a nightmarish flower with its petals partly enclosing a sphere, and it can reset time to a point about 24 hours earlier. All of the mimics are telepathically connected and share a “hive mind.” Whenever an alpha dies, the Omega immediately senses its loss via the psychic link, and it resets time. That dead alpha, along with any other mimics that died between intervals, is resurrected, but with intact memories of what happened in all the previous time cycles.

This setup is the basis of the mimics’ combat prowess because it lets them experiment with different strategies and tactics against their human enemies without risk of losing. If a mimic attack is defeated and the alpha leading that attack is killed, then a time reset happens and the mimics attack again, but adjust their battlefield tactics to overcome or avoid whatever caused their defeat previously. This process is repeated as many times as is needed for the mimics to win. It’s no different from a video game player saving his game right before a challenging battle against an NPC enemy that he knows will probably kill him, and then repeatedly reloading the game from that save point to fight the boss over and over until he finally wins. During each battle, the human player learns a little more about his enemy’s strengths, weaknesses, and tactics, and attenuates his own fighting style accordingly.

When Tom Cruise died on the beach the first time, the alpha’s blood entered his bloodstream, infusing Cruise with the same telepathic link to the mimic collective, and with the ability to make the Omega reset time whenever he dies. With this knowledge, Tom Cruise partners with Emily Blunt to find a way to kill the Omega, regardless of how many time cycles it takes to locate it and find its vulnerability. Without the time reset ability, the remaining mimics will be slowly destroyed by human military forces.

I thought Edge of Tomorrow was a respectable movie overall. It was entertaining, had great special effects (the alien design and their social structure were very creative), and for an action sci-fi film marketed at mass audiences, its plot was surprisingly complex. It was neither one of the best nor worst films of the genre, but I still recommend it.

Analysis:

There will be powered combat exoskeletons. Along with the aliens, the defining sci-fi element in the film is the powered combat exoskeletons. The outfits, which are called “Combat Jackets,” give their wearers super strength, enormous firepower, and provide some ballistic protection (though the value is questionable since the aliens’ bullets and sharp tentacles seem to always penetrate it). The exoskeletons are also powered by single batteries about the size of VHS tapes. Exoskeletons like these doesn’t exist, there are no signs they will be created anytime soon, and I have doubts they will ever be practical for battlefield use.

Left: A combat exoskeleton from the movie
Right: An industrial exoskeleton (the “Guardian XO”) from real life

The main reason why combat exoskeletons don’t exist is lack of a portable power source for them. It takes a lot of energy to move around heavy metal arms and legs, all while bearing the weight of weapons, armor and other equipment attached to the exoskeleton, as well as the weight of the human operator’s body. To put this into perspective, one of today’s most advanced exoskeletons, the “Guardian XO” made by Sarcos Robotics, needs a battery pack the size of a large briefcase to operate for eight hours. Since that figure hasn’t been independently verified and is instead being claimed by Sarcos without any supporting data, the actual operating time on a single charge is probably significantly lower. Additionally, the Guardian XO is intended for use in controlled factory environments where the operator mostly stays in one place and slowly lifts heavy objects up and down. In a combat situation where the wearer would be sprinting, jumping, marching long distances, and rapidly moving their arms and pirouetting their bodies to aim weapons at enemies, the rate of energy consumption would be much higher. If you wore a Guardian XO into combat, the machine might be out of juice in three hours, turning into a useless, heavy encumbrance you’d have to wriggle out of like a wrecked car.

In the film, an exoskeleton needs only one battery that is the size of a VHS tape.
In reality, the Guardian XO exoskeleton’s battery pack is the size of a large briefcase. The pack is mounted on the wearer’s back and consists of three, large batteries (a single unit is shown at left). It is around 30 times LESS energy-dense than the batteries in the film.

You can’t take a big piece of personal equipment into battle if you know it will stop working after a short time, putting your life at risk. That said, I don’t think combat exoskeletons will be worth considering until they’re able to run at least 24 hours on a single battery that is no bigger than the Guardian XO’s backpack. This would probably require batteries that are at least five times more energy-dense than today’s standard lithium-ion batteries, meaning growth from 260 Wh/kg to 1,300 Wh/kg, which is as energy dense as gasoline. I’m not sure if chemistry even allows for batteries or “battery-looking” solid media like fuel cells and capacitors to be that energy-dense AND stable, but assuming it is, then we should achieve this level of technology in 33 years if the long-term 5% average yearly rate of battery improvement continues (recall that I’ve predicted battery-powered airplanes will become practical around the same time).

Even if the power supply problem were solved, there are more potential deal breakers that could keep combat exoskeletons from the battlefield. The risk of accidental injuries to wearers and their comrades might prove unacceptable. If you tripped over a log and face-planted on the ground in just the wrong way, the weight of your big backpack battery and portions of your metal frame could snap your neck. If you were wearing a 200 lb, rigid metal suit, and you fell backwards while climbing a hill and rolled over the un-armored people behind you, it could be a multi-casualty, mission-ending disaster. Simply swinging your super-strong, metal-encased arm out to the side could send an unseen comrade to the hospital if it accidentally connects with his face.

The risks of self-injury to wearers could be mitigated if the exoskeletons fully enclosed the wearer’s body. For example, head and neck injuries could be prevented if the exoskeleton had an integral, full-head helmet, like the atmospheric diving suit shown above. Since it must withstand the crushing pressure of the deep sea, the clear visor is doubtless very strong and can be thought of as an integral part of the rigid exoskeleton suit. If the man were wearing the suit and he fell forward while waddling around a parking lot and his faceplate landed on the curb, the force of the impact would be absorbed by the whole exoskeleton, not transmitted into his face and neck, and his injuries would be minimal. Likewise, if a squad of soldiers were wearing powered exoskeletons like that, then the risks of them accidentally hurting each other would be much lower since each man’s armor would absorb the force of accidental physical contact with the other men. Being fully enclosed in heavy armor also has obvious value blocking enemy bullets.

Problematically, a fully enclosed exoskeleton would be heavy and would introduce the new problem of overheating the wearer, in turn mandating the incorporation of a body cooling system. The extra weight of the armor and cooling system and their drain on the exoskeleton’s power supply could easily plunge the whole system into an engineering “death spiral” of irreconcilable requirements. Additionally, full-body armor would make it hard for the wearer to move around his limbs, limiting his ability to aim his weapons and even just to walk. Crouching down to avoid gunfire would be harder, and getting into a prone position might become impossible, which would be unacceptable. And if the exoskeleton were too bulky, the wearer wouldn’t be able to fit through the doors of standard military vehicles, and he might get so wide that he’d take up two seats, forcing the deletion of another member of the infantry squad (is one soldier in an exoskeleton better than two soldiers without?). Treating an injured comrade while he was stuck in his exoskeleton would also be challenging and would add to the “user risk” problem. These tradeoffs probably wouldn’t make it worth it to put average soldiers in fully enclosed exoskeletons, or even “mostly enclosed” ones.

The “EksoGT” exoskeleton for disabled people.

With these facts in mind, I’m left unsure if it will ever make sense for humans to wear powered combat exoskeletons into battle. If it does make sense, then the most realistic type would probably be a minimalist exoskeleton meant to increase the amount of weight a human soldier could carry on patrols. It would have boots connected to segmented legs, in turn connected to a metal frame supporting the wearer’s hips and back, similar to the real-life “EksoGT” shown above. Instead of a soldier slinging a heavy backpack over his shoulders and getting physically exhausted during a march by straining against its weight with each step, the soldier could put on an exoskeleton and attach the backpack to the suit’s metal frame. The weight would be borne entirely by the frame, allowing the soldier to go on long patrols without getting as tired, and to carry more gear than would otherwise be possible.

An articulating “third arm” like this could let an exoskeleton soldier carry and fire a very heavy weapon. One end of the arm would attach to the torso portion of the exoskeleton, and the other would be attached to the weapon. The weapon’s weight would be entirely supported by the exoskeleton’s metal frame, and not by the human’s muscles.

These kinds of exoskeletons could also allow wearers to carry and fire weapons that are too heavy for unaided humans to bear, like .50 cal machine guns and automatic grenade launchers, giving their infantry squads a huge increase in firepower. Instead of adding two robot arms to the exoskeleton to let the wearer carry such heavy weapons, it might make more sense to copy the infantry kit setup from Aliens and to attach a Steadicam rig to the exoskeleton’s frame, and then use the tip of the Steadicam as the weapon’s mounting point.

Minimalist exoskeletons like this wouldn’t have the potentially dealbreaking weaknesses I described earlier. Since they would be lightweight, they wouldn’t pose serious injury risks to comrades if a soldier wearing one of them accidentally stepped on someone else’s foot or fell on top of them. The low weight also means the battery pack’s size and lifespan would be practical for field use. Since the exoskeletons wouldn’t enclose their wearers in armored shells, overheating wouldn’t be a problem, and cooling systems would be unnecessary. Since they wouldn’t give their wearers super-strength, there would be no risk of accidental injury from that source. And so on…

Still, there would be important limitations. Battery life limitations would prohibit the exoskeletons from being used on multi-day missions where logistical support (e.g. – someone else giving you fresh batteries) could not be guaranteed. Thus, I think they would only be used for missions expected to take less than 24 hours, like daylong patrols where the plan was to go back to a base at the end. Another limitation is that wearing an exoskeleton would hurt the soldier’s mobility in some ways: Certain leg movements like crouching down and walking laterally would be harder to do. The weight of the exoskeleton and of any objects strapped to it could make it harder for the soldier to stay balanced on his feet. Overall though, the benefits could outweigh the downsides.

The other type of exoskeleton that might make sense is a fully-enclosed, heavily armored suit meant for quick, pre-planned raids, like the attack on Osama bin Laden’s house, or rescuing hostages from a building full of militants. In those kinds of missions, the extreme risk of close-quarters gunfire would demand full body armor, and it would be so heavy that only a powered exoskeleton could bear it. The concordant reduction in battery life wouldn’t be a problem due to the shortness of the combat–it would only need to work for an hour before the bad guys were all dead and the friendly troops were extracted. Super-strength would also be of real value given the chance of hand-to-hand combat in close quarters. The psychologically intimidating effect of attacking people while wearing a suit of heavy armor would also be beneficial. And if all the commandos were wearing exoskeletons, they wouldn’t be able to accidentally hurt each other.

In summary, I predict that combat exoskeletons could be practical and in common use among the most advanced militaries and military/police commando groups as early as the 2050s. At least 30 years will be needed to batteries to improve enough to make them practical for field use, and for other technological kinks to get worked out. Powered exoskeletons designed for less critical tasks, like factory/construction work and aiding people with spinal cord problems, will become practical earlier.

Humans in powered combat exoskeletons will dominate warfare forever. OK, so Edge of Tomorrow only shows a snapshot in time–an alternate 2020–and doesn’t tell us whether exoskeleton soldiers will still be the apotheosis of ground warfare in 2040, 2100, or the year 3000. This means I’m putting words in the film’s mouth in a sense, but this is an important point I need to bring up somehow: Even if the exoskeletons get really, really advanced and powerful, they will inevitably be rendered obsolete by unmanned weapons. This is because the central component of an exoskeletoned soldier is a human being with a flimsy body made of flesh and bone, and who needs hours of sleep and rest per day. As I discussed in my Terminator Dark Fate review, humans will inevitably become the weakest links in all combat systems, and will thus be inferior to all-mechanical counterparts.

A scene from Edge of Tomorrow illustrates this point. During the invasion, Tom Cruise and his squad ride to the beach in a cargo helicopter. The plan is for the craft to drop to low altitude and hover over the beach while its belly opens up like a bomber and the troops dismount by rappelling down to the sand on ropes. Unfortunately, enemy ground fire critically hits the helicopter a minute before the planned disgorging of its load, so Tom Cruise and the others have to jump out of the stricken craft at higher altitude or die in an explosion. There’s then a spectacular jump sequence that ends with Tom Cruise free-falling about 30 feet to the ground, slamming the front of his body and face into the wet sand. He is shaken by this, but unhurt, and the same is true for his comrades who fell the same distance.

In reality, the fall would have hurt Tom Cruise and several of the others so much that they wouldn’t have been able to get up and fight. Even though the exoskeletons were made of strong metal that might not have been scratched by the impact with the ground, the bodies of the humans inside the exoskeletons were made of weak flesh and bone, which would have been damaged by the abrupt change in velocity. Machines can be much more durable than the soft humans that are being flung around against the hard surfaces inside of them.

The frailties of the human body are already the limiting factor of fighter plane performance. When a plane makes a sharp left or right turn, the aircraft and the pilot experience G-forces (you also feel it when you make a sharp turn while driving your car). As shown in the graph above, the intensity of the G-force has an exponential relationship with the sharpness of the turn (“Bank Angle” expresses how sharp the turn is). A human pilot can’t withstand more than 9 G’s before he passes out from the physical strain on his body, but his aircraft can endure 15 G’s before its metal parts break apart. This means the human effectively limits the aircraft’s performance below its theoretical maximum, and by extension, it means that, in a dogfight, an autonomous fighter plane with a computer pilot could outmaneuver a human-piloted fighter plane.

Humans are becoming the weakest link in fighter plane combat, and farther in the future, we will also become the weakest links in ground combat. That means humans in combat exoskeletons will be inevitably rendered obsolete by some kind of purely mechanical fighting machine that isn’t hurt by 30-foot falls, doesn’t feel fear, doesn’t need to sleep, and doesn’t have fleshy eardrums that can be blown out by nearby explosions and heavy gunfire. There may be a period of time where humans in exoskeletons are the pinnacle of ground warfare, but this will give way to an era of full mechanization.

Human soldiers will use powered exoskeletons for hand-to-hand combat. In several scenes, soldiers use their exoskeletons’ mechanically amplified strength to punch aliens and objects with superhuman force. Tom Cruise kills at least one alien this way, and his girlfriend uses her strength to casually punch a car door out so it detaches from its hinges and skids across the ground. If powered combat exoskeletons become common, few of them will grant users amplified hand-to-hand fighting abilities like this.

An awesome shot of Tom Cruise punching an alien to death.

As I wrote earlier, powered combat exoskeletons will probably be used to bolster the endurance and load-carrying capacity of infantrymen. Exoskeletons designed for that would not necessarily have features that also let the user punch or kick things with greater than normal force. For example, since my minimalist exoskeleton lacks arms, it wouldn’t empower its wearer to punch harder or lift heavier things. The Steadicam mount would be like a strong, third arm that could prop up guns but do nothing else that a human arm does, like punching.

Even if exoskeletons amplified their wearers’ strength, it would be of very little direct benefit in combat since hand-to-hand fighting is extremely rare on the modern battlefield, and there’s no reason to think that will change in the future. If anything, average kill distances will increase thanks to smarter weapons. Endowing soldiers with the ability to punch and kick with superhuman force would also make accidental injuries to oneself and nearby comrades more common and more severe, potentially outweighing the small benefits of being able to strike enemies harder.

Superhuman strength will probably only be useful in the “fully-enclosed, heavily armored suit meant for quick, pre-planned raids” that I envisioned earlier. A squad of men wearing such suits wouldn’t be able to accidentally hurt one another with their super-strength since their full-body armor would protect them. Hand-to-hand combat would also be much likelier in the kinds of close-quarters missions the suits would be used for, making super-strength a real advantage.

Let me finally note that I liked how Tom Cruise’s exoskeleton enclosed most of his hand in a big, metal “glove.” It was a small but important detail, since it let him punch things without crushing all the bones in his hand. The front of the rigid, metal glove connected with the surface of whatever he was punching, and the force of the impact was transmitted from the glove to his suit’s metal arm, and then into the metal torso portion of his exoskeleton, meaning the frame bore the superhuman forces of his punches, and none of it was transmitted into the soft tissues of his body, sparing him injury. Exoskeleton suits designed for augmented, hand-to-hand combat would need to enclose their wearers’ hands and feet to prevent operator injury.

There will be tilt-engine aircraft that are bigger and better than the V-22. In the film, the human military has large utility aircraft with four engines that can tilt, transforming the aircraft from helicopters into planes. They use many of these tilt-rotor aircraft to transport the exoskeleton troops to the battle zone. These kinds of aircraft don’t exist, the best we have in real life is the much smaller V-22 (which only has two tilt-engines), and I doubt anything like the aircraft shown in the film will exist for at least 20 years.

An assortment of military aircraft, including the fictitious four-engine tilt-rotor planes, and real two-engine tilt rotor V-22s, plus older two-rotor CH-47 helicopters.

Consider that the V-22 development program started in 1982, the first prototype wasn’t made until 1988, and internal testing and redesigns went on until 2005, when the aircraft’s kinks were finally worked out and it entered mass production. In other words, it took 23 years for the V-22 to go from formal concept to a combat-ready aircraft (and that label is debatable since it suffered from serious problems after 2005 that took more time to fix).

The American V-22 Osprey has two rotors than can swivel up and down, letting it take off straight up into the air like a helicopter, and then fly forward like an airplane.

If we wanted to build a new tilt-rotor aircraft that was bigger and more complicated than the V-22, then the latter’s 23 year development timetable provides a benchmark for how long it would take. If the aircraft used a more advanced type of propulsion, like the tilting turbofan engines the Skynet’s planes had in Terminator, then it would be even longer. Granted, if we were invaded by aliens and desperately needed better weapons, the project would get more money and manpower and would go faster. It’s also possible that some development time could be shaved off by carrying over engineering and project management lessons learned during the V-22’s development. That said, even if we had all our ducks in a row, I doubt we could make such an aircraft in less than ten years. Returning to the real world, we are not grappling with an alien invasion and no major country is planning to sharply increase its military R&D budget, so the ~20 year timetable to go from a government announcing it is willing to pay money for an advanced aircraft with XYZ characteristics to a fully functional aircraft is most likely. This means there won’t be anything like the quad-tilt-rotor aircraft in Edge of Tomorrow until 2040 at the earliest.

It will probably take longer than that since the 20 year end date assumes that the development process starts now, in 2020. In fact, no military has announced a serious desire for such an aircraft, nor does any look poised to do so. The V-22 still hasn’t proven its worth, and history might someday look on it as an expensive failed experiment like the Concorde or the Space Shuttle. Until it does so, there will be no demand for even bigger, more expensive tilt-rotor aircraft. (Note that the U.S. military has a program called “Future Vertical Lift,” whose goal it is to make tilt-rotor aircraft that are smaller than the V-22. It may or may not be cancelled.)

There will be 3D volumetric displays. In one film scene, the characters look at a tabletop volumetric projection of their alien opponents. The display is highly detailed, runs silently, and is treated with some disinterest, indicating it is an established technology. As I wrote in my Prometheus review, the current state of this technology is underdeveloped, and it will be many decades before the kinks are worked out and it becomes practical. Even once it becomes a mature technology, it could be muscled out of use by competing technologies.

“Monocular passive ranging” can be an accurate way to find how far away an object is. If you’re looking at camera footage of the object, it’s obviously better to have a higher resolution camera so the object appears as many pixels.

A lens-less, single-pixel digital camera can produce highly detailed images of what it sees. “The reason the single-pixel camera can make do with one light sensor is that the light that strikes it is patterned. One way to pattern light is to put a filter, kind of like a randomized black-and-white checkerboard, in front of the flash illuminating the scene. Another way is to bounce the returning light off of an array of tiny micromirrors, some of which are aimed at the light sensor and some of which aren’t. “
I wonder if we could use this technology to vision distant exoplanets without having to build gigantic telescopes in space.

If all human-driven vehicles were banned from Manhattan and only autonomous taxis were allowed, the city could meet its surface transit needs with only half as many cars as today. I think it would be even more efficient if the taxis were mostly Smartcars since their footprints are only half as big as the footprints of fullsize cars that currently serve as taxis, meaning they would almost double the capacity of the city’s existing road network.

The NTSB has found that the fatal 2018 crash of a Tesla was only partly due to the limitations of the car’s autopilot feature, which was on at the time. The human driver was playing a game on his smartphone at the moment of impact even though he knew the car had problems negotiating that stretch of the road, and the crash attenuator that the vehicle plowed into had been compacted by a previous car accident and not promptly replaced by the state highway administration.

“As I envision the process, whoever is sending a package will simply place it on their front doorstep and take a photo of it with a special shipping app on their phone. This will start the process, detailing the package size, dimensions, and GPS coordinates, and the sender will add particulars such as destination, level of urgency and weight category (i.e. under 10 lbs). Within a short while, a robotic pickup service will arrive, retrieve the package, and load it onto a drone delivery vehicle.”

“Phytomining” is a practice in which certain species of plants are grown in a patch of ground to extract metals from the soil. Different kinds of plants are known to preferentially suck up different types of metals dissolved in the soil into their roots and up to their stems and leaves. After some time, the farmer cuts down the plants and uses chemicals to leech out and purify the metals in them. Phytomining could be used to clean toxic metal residues from soils and to mine precious metals like gold.

Because Mars is farther away from the Sun, the planet receives less sunlight than Earth does. Put simply, the Sun always looks dimmer on Mars.
“The maximum solar irradiance on Mars is about 590 W/m2 compared to about 1000 W/m2 at the Earth’s surface.”

The Germans were smart enough to build four-engine bombers like the U.S. and Britain had, but they never did thanks to bad doctrinal decisions made before WWII. The four-engine-but-only-two-propeller He-177 was the best they had.

Older tanks like the U.S. M-60 and the Soviet T-55 will never be as good as newer tanks because of their armor. The older tanks’ armor was just made of steel. As anti-tank weapons got more potent, the solution was to simply thicken the steel armor. Engineers realized that this trend was unsustainable since it would lead to future tanks that were too heavy to move, so they shifted to a new paradigm by inventing “composite tank armor,” which is a material made of multiple layers of different materials like quartz, ceramic, and relatively thin steel. It was lighter and more protective than thick, solid steel alone. The U.S. M1 Abrams and Soviet T-64 were the first tanks to have composite armor. Since armor is integral to a tank in the same way that your skin and flesh are integral to your body, there’s no way to “upgrade” older tanks like the M-60 that are made of solid steel in a way that will put their armor protection on par with new tanks that have composite armor. Thus, the M-60 is, on the modern battlefield, effectively carrying around many tons of dead weight that can’t be removed.

“Stowed kills” is the word of the day. It is a numerical value that averages the amount of ammunition a tank has with the power of those rounds to express how many enemy vehicles it can destroy before running out. There’s a simple tradeoff: Bigger ammunition hits harder and has longer range, but because of its size, you can’t fit as much of it in your tank. Larger ammunition can also accommodate internal, programmable sensors and computers the smaller ammo can’t (yet).
