Review: “Blade Runner”

Plot:

In the year 2019 a race of “bioengineered” humans called “replicants” exists, and are used as slave laborers and soldiers on space colonies. While made superior to ordinary humans in most respects (strength, pain tolerance, intelligence), replicants have deliberately capped lifespans of only four years to limit the amount of damage they can do should they rebel against their masters, and they are not allowed on Earth itself. This doesn’t stop a small group of replicants–including several who have enhanced combat traits–from hijacking a space ship and traveling to Earth to confront their “creator,” the head of the company the manufactured them and all other replicants, and to force him to technologically extend their lifespans. The replicants smuggle themselves into Los Angeles, where the company’s headquarters is.

Upon discovering the infiltration, the LAPD hires a bounty hunter named “Rick Deckard” to hunt down the replicants. Deckard’s background is never clearly explained, but he has good detective skills and has killed replicants before. As he follows leads and tracks them down, Deckard meets a love interest and is forced to confront his biases about replicants and consider existential questions about them and himself.

An important fact must be clarified and emphasized. Replicants ARE NOT robots or androids; they are “bio-engineered” humans. They don’t have metal body parts or microchip brains, and instead are made of flesh and blood like us. As proof, there are several scenes in Blade Runner where the replicant characters are hurt or killed, and they display pain responses to injuries and bleed red blood.

A replicant named “Zhora,” dead after being shot in the back with a handgun. Note the blood.

Additionally, it’s made clear that replicants can only be distinguished from humans by a sit-down interview with a trained examiner in which the subject is asked a series of odd questions (called the “Voight-Kampff Test”) while their physiological and spoken responses are analyzed. The procedure looks like a polygraph test. If replicants were robots with metal bones, microchip brains, or something like that, then a simple X-ray scan or metal detector wand would reveal them, and there’d be no need for a drawn-out interview. Likewise, if the replicants were organic, but fundamentally different from humans, then this could also be quickly detected with medical scans to vision their bones and organs, and with DNA tests to check for things like something other than 46 chromosomes.

By deduction, it must be true that replicants are flesh-and-blood humans, albeit ones that are produced and birthed in labs and biologically/genetically engineered to have trait profiles suited for specific jobs. The available evidence leads me to suspect that replicants are “assembled” in the lab by fitting together body parts and organs, the way you might put together a Mr. Potato Head. They are then “born” as full-grown adults and come pre-programmed with fake memories and possibly work skills. Replicants are human slaves, technologically engineered for subservience and skill.

Analysis:

Los Angeles will be polluted and industrial. In the film, Los Angeles is a grim, hectic place where fire-belching smokestacks are within sight of the city’s residential core. During the few daylight scenes, the air is very hazy with smog. This depiction of 2019 fortunately turned out wrong, and in fact, Los Angeles’ air quality is much better than it was when Blade Runner was released in 1982.

This improvement hasn’t just happened to L.A.–across the U.S. and other Western countries, air pollution has sharply declined over the last 30-40 years thanks to stricter laws on car emissions, industrial activity, and energy efficiency. With average Westerners now accustomed to clean air and more aware of environmental problems, I don’t see how things could ever backslide to Blade Runner extremes, so long as oxygen-breathing humans like us control the planet.

Of course, the improvements have been largely confined to the Western world. China and India–which rapidly industrialized as the West was cleaning itself up–now have smog levels that, on bad days, are probably the same as Blade Runner’s L.A. This has understandably become a major political issue in both countries, and they will follow the West’s path improving their air quality over the coming decades. In the future, particulate air pollution will continue to be concentrated in the countries that are going through industrial phases of their economic development.

Real estate will be cheap in Los Angeles. One of the minor characters is a high-ranking employee at the company that makes the replicants. He lives alone in a large, abandoned apartment building somewhere in Los Angeles. After being tricked into letting the replicants into his abode, he gestures to the cavernous space and says: “No housing shortage around here. Plenty of room for everybody.” In fact, the exact opposite of this came true, and Los Angeles is in the grips of a housing shortage, widespread unaffordability of apartments and houses, and record-breaking numbers of poorer people having to live on the streets or in homeless shelters.

The problems owe to the rise of citizen groups that oppose new construction, historical preservationists, and innumerable new zoning, environmental, and labor laws that have made it too hard to build enough housing to keep up with the city’s population growth since 1982, and priced affordably for the people who actually work there. Blade Runner envisioned a grim 2019 for Los Angeles, courtesy of unchecked capitalism (e.g. – smokestacks in the city, smoggy air, megacorporations that play God by mass producing slaves), yet the city (and California more generally) actually went down the opposite path by embracing citizen activism, unionists, and big government, ironically leading to a different set of quality of life problems. Fittingly, the building that stood in for the derelict apartment building in Blade Runner has now been fully renovated, is a government-protected landmark, and is full of deep-pocketed, trendy businesses.

The vast majority of Los Angeles’ land area is covered by single-family homes and low-rise buildings.

There will be flying cars. One iconic element of Blade Runner is its flying cars, called “spinners.” They’re shaped and proportioned similarly to conventional, road-only cars, and they’re able to drive on roads, but they can also take off straight up into the air. Clearly, we don’t have flying cars like this today, and for reasons I discussed at length in my blog entry about flying cars, I doubt we ever will.

I won’t repeat the points I made in that other blog entry, but let me briefly say here that the spinners are particularly unrealistic types of flying cars because they don’t have propellers or any other device that lifts the craft up by blowing air at the ground. Instead, they seem to operate thanks to some kind of scientifically impossible force–maybe “anti-gravity”–that lets them fly almost silently. There are brief shots in the film where low-flying spinners belch smoke from their undersides, which made me wonder if they were vectored thrust nozzles like those found on F-35 jets. But because the smoke comes out at low speed, the undermounted nozzles are not near the crafts’ centers of gravity, and the smoke isn’t seen coming out when the spinners are flying at higher altitudes, I don’t think they help levitate the spinners any more than a tailpipe helps a conventional car drive forward on a road.

People will smoke indoors. In several scenes, characters are shown smoking cigarettes indoors. This depiction of 2019 is very inaccurate, though in fairness the people who made the movie couldn’t have foreseen the cultural and legal sea changes towards smoking that would happen in the 1990s and 2000s.

People in Blade Runner like smoking indoors. No one stops them, and there aren’t any “No Smoking” signs.

When judging the prediction, also consider that if we average people and the legal framework were more enlightened, vaping indoors would be much more common today. While not “healthy,” vaping nicotine is vastly less harmful to a person’s health than smoking cigarettes, and science has not yet found any health impact of exposure to “secondhand vape smoke.”

There will be genetically engineered humans. In Blade Runner, mankind has created a race of genetically engineered humans called “replicants” to do labor. The genetic profile of each replicant is tailored to the needs of his or her given field of work. For example, one of the film’s replicant characters, a female named “Pris,” is a prostitute, so she is made to be physically attractive and to have average intelligence. All of the replicant characters clearly had high levels of strength and very high pain tolerances.

Digital dossier on the replicant “Pris”

In the most basic sense, Blade Runner was right, because genetically engineered humans do exist in 2019. There are probably dozens of people alive right now who were produced with a special in vitro fertilization (IVF) procedure called “mitochondrial replacement therapy” in which an egg from a woman with genetically defective mitochondria is infused with genetically normal mitochondria from a third person, and then the “engineered” egg is combined with sperm to produce a zygote. The first such child was born in 1997.

Additionally, there are now two humans with genetically engineered nuclear DNA, and they were both born in November 2018 in China after a rogue geneticist used CRISPR to change both of their genomes. Those edits, however, were very small, and will probably not manifest themselves in any detectable way as the babies grow up, meaning Blade Runner‘s prediction that there would be genetically engineered adults with meaningfully enhanced strength, intelligence, and looks in 2019 failed to come true. This is because it has proven very hard to edit human genes without accidentally damaging the target gene or some other one, and because most human traits (height, IQ, strength, etc.) are each controlled by dozens or hundreds of different genes, each having a small effect.

For example, there’s no single gene that controls a human’s intelligence level; there are probably over 1,000 genes that, in aggregate, determine how smart the person is and in what areas (math, verbal, musical). If you use CRISPR to flip any one of those genes in the “smart” direction, it will raise the person’s IQ by 1 point, so you just have to flip 40 genes to create a genius. But CRISPR is an imprecise tool, so every time you use it to flip one gene, there’s a 20% chance that CRISPR will accidentally change a completely different gene as well, perhaps causing the person to have a higher risk of cancer, schizophrenia or a birth defect.

The discovery of CRISPR was a milestone in the history of genetic technology, and it improved our ability to do genetic engineering by leaps and bounds, but it’s simply not precise enough or safe enough to make humans with the major enhancements that the replicants had. We’ll have to wait for the next big breakthrough, I can’t predict when that will happen, and I doubt anyone else could since there’s no “trend line” for this area of technology.

That’s not to say that we couldn’t use existing (or near-term) genetic technologies to make humans with certain attributes. A technique called “preimplantation genetic screening” (PGS) involves the creation of several human zygotes through IVF, followed by gene sequencing of each zygote and implantation of the one with the best genetic traits in the mother. This isn’t true “genetic engineering,” but it accomplishes much the same thing. And you could sharply raise the odds of getting a zygote with specific characteristics if you did the IVF using sperm or eggs from adults who already had those those characteristics. For example, if you wanted to use genetic technology to make a physically strong person, you would get the sperm or eggs of a bodybuilder from a sperm/egg bank, use them for an IVF procedure, and then employ PGS to find the fertilized egg that had the most gene variants known to correlate with high strength. This would almost certainly yield a person of above-average physical strength, without making use of bona fide “genetic engineering.” There are no statistics on how many live babies have been produced through this two-step process, but if we assume just 0.1% of IVF procedures are of this type, then the number is over 8,000 globally as of this writing.

Furthermore, I can imagine how, within 20 years, genetic engineering could be applied to enhance the zygotes farther. Within that timeframe, we will probably discover which mitochondrial genes code for athleticism, and by using mitochondrial replacement therapy, we could tweak our PGS-produced zygote still farther. Let’s assume that there are ten nuclear genes coding for physical strength. The average person has five of those genes flipped to “weak” and five flipped to “strong,” resulting in average overall strength. Our carefully bred, deliberately selected zygote has nine genes flipped to “strong” and one flipped to “weak.” Since we only have to change one gene to genetically “max out” this zygote’s physical strength, the use of CRISPR is deemed an acceptable risk (error rates are lower than they were in 2019 anyway thanks to lab techniques discovered since then), and it works. The person grows up to be a top bodybuilder.

There will be genetically engineered super-soldiers. The leader of the replicant gang in Blade Runner is named “Roy Batty,” and he was designed with traits suited for military combat. Having governments or evil companies make genetically engineered or cloned super-soldiers is a common trope in sci fi, but I doubt it will ever happen, except perhaps in very small numbers.

First, I simply don’t believe that the government of any free country, and even most authoritarian ones, would be willing to undertake such a project. And even if one of them were, the diplomatic costs imposed by other countries on the basis of human rights would probably outweigh the benefits of having the small number of super-soldiers. Mass producing millions of super-soldiers to fill out an army (to be clear, there was no evidence of anything but than small-batch production in Blade Runner) is even less plausible, as it would be too fascist and dehumanizing a proposal for even the most hardline dictatorships. Censure from the international community would also be severe. What damage can you do with an army of genetic super-soldiers if years of economic sanctions have left you without any money for bullets?

Second, a country’s ability to make super-soldiers will be constrained by its ability to raise and educate them. In spite of their genetic endowments, the super-soldiers would only be effective in combat if they were educated to at least the high school level and psychologically well-adjusted, which means costly, multi-year investments would need to be made. Where would the state find enough women who were willing to be implanted with super-soldier embryos and carry them until birth? If the government coerced its women into doing this, the country would become an international pariah for sure, and its neighbors would strengthen their own armies out of concern at such derangement.

Who would raise the children? State-run orphanages are almost universally terrible at this, and too many of the super-soldiers would turn out to be mentally or emotionally unfit for military service, or perhaps fit, but no better overall than a non-genetically engineered soldier who was raised by a decent family. If the government instead forced families to raise the super-soldier kids, doubtless many would be damaged by family dysfunction at the hands of parents who didn’t want them or parents who raised them improperly.

Third, by the time we have the technology to make genetic super-soldiers at relatively low cost, and by the time any such super-soldiers get old enough to start military service, militaries will probably be switch to AIs and combat robots that are even better. As I predicted in my Starship Troopers review, a fully automated or 95% automated military force could exist as early as 2095.

And if the super-soldiers were all clones of each other, they could develop very close personal bonds, come to feel alienated from everyone else, and behave unpredictably as a group. Identical twins and triplets report having personal bonds that can’t be understood by other people.

That said, I think human genetic engineering will become widespread this century, it will enable us to make “super people” who will be like the most extraordinary “natural” humans alive today, some of those genetically engineered people will serve in armed forces and under private military contractors across the world, and they will perform their jobs excellently thanks to their genetically enhanced traits. While it’s possible that some of these “genetic super-soldiers” will be made by governments or illegally made by evil companies, people like that will be very small in number, and dwarfed by genetic super-soldiers who are the progeny of private citizens who decided, without government coercion, to genetically engineer their children. Those offspring will then enter the military through the same avenues as non-genetically engineered people, either by joining voluntarily or being drafted. Yes, there will be genetically engineered super-soldiers someday, but their presence in the military or in private security firms will be incidental, and not–except in some rare cases–because a government or company made them for that purpose and controlled their lives from birth.

There will be “artificial animals”. While visiting the luxurious office of a tycoon, Deckard sees the man’s pet owl flying around, and he’s told that it is “artificial.” Later, he comes across an artificial pet snake, whose scales (and presumably, all other body parts) were manufactured in labs and bear microscopic serial numbers. To the naked eye, both animals look indistinguishable from normal members of their species. It’s unclear whether “artificial” means “organic” like human replicants, or “mechanical” like robots with metal endoskeletons and computer chips for brains. We have failed to create the latter, and the robotic imitations of animals we have today are mostly toys that don’t look, move, or behave convincingly. Our progress achieving the former (replicant animals) is more equivocal.

Our technology is still far too primitive for us to be able to grow discrete body parts and organs in a lab and to seamlessly join them together to make healthy, fully functional animals. This is the likeliest process used to make the replicants, so in the strictest sense, we have failed to live up to vision Blade Runner had for 2019. However, we are able to genetically modify animals and have done so many times to hone our genetic engineering techniques. For example, Chinese scientists used CRISPR to make dogs that have twice the normal muscle mass. For all I know, they’re now the pets of a rich man like the film’s tycoon.

Additionally, we are reasonably good at cloning animals, and, considering the vagueness of the terms “artificial” and “bioengineered” as they are used in the film, it could be argued that they apply to clones. Cloning a cat costs about $25,000 and a dog about $50,000, putting the service out of reach for everyone but the rich, and there are several rich people who have cloned pets, most notably Barbra Streisand, who had two clones made of her beloved dog after it died. A celebrity of her stature owning cloned animals is somewhat analogous to Blade Runner‘s depiction of the tycoon who owned the artificial owl.

There will be non-token numbers of humans living off Earth. At several points in Blade Runner, references are made to the “off-world colonies,” which are space stations and/or celestial bodies that have significant human populations. Advertisements encourage Los Angelinos to consider moving there, which implies that the colonies are big enough and stable enough to house people other than highly trained astronauts. The locations of the colonies aren’t described, but I’ll assume they were in our solar system.

This prediction has clearly failed. The only off-world human presence is found on the International Space Station, it only has a token number of people (about six at any time) on it, only elite people can go there, and its small size and lack of self-sufficiency (cargo rockets must routinely resupply it) means it fails to meet the criteria for a “colony”.

There are no plans or funds available to expand the ISS enough to turn it into a true “space colony,” and in fact, it might be abandoned in the 2020s. Other space stations might be built over the next 20 years by various nations and conglomerates, but they will be smaller than the ISS and will only be open to highly trained astronauts.

While a manned Moon landing is possible in the next ten years (probably by Americans), I doubt a Moon base comparable in size and capabilities to the ISS will be built for at least 20 years (note that 14 years passed from when U.S. President Reagan declared the start of the ISS project and when the first part of it was launched into space, and no national leader has yet committed to building a Moon base, which would probably be even more expensive). In fact, in my Predictions blog post, I estimated that such a base wouldn’t exist until the 2060s. It would take decades longer for that base or any other on the Moon to get big enough to count as a “colony” that was also open to large numbers of average-caliber people. A Mars colony is an even more distant prospect due to the inherently higher costs and technological demands.

I think the human race will probably be overtaken by intelligent machines before we are able to build true off-world colonies that have large human populations. Once we are surpassed here on Earth, sending humans into space will seem all the more wasteful since there will be machines that can do all the things humans can, but at lower cost. We might never get off of Earth in large numbers, or if we do, it will be with the permission of Our Robot Overlords to tag along with them since some of them were heading to Mars anyway.

Cars will be boxy and angular instead of streamlined. Many of the cars shown in the movie are boxy and faceted. While this may have looked futuristic to Americans in 1982, boxy, angular cars were in fact already on their way out, and would be mostly extinct by the mid-90s. The cars of Blade Runner look retro today, and no mass-produced, modern vehicles look like them.**

U.S. fuel economy standards sharply increased from 1975-85. Blade Runner was filmed in 1982, and its artistic vision was to some extent influenced by the aesthetics of the time, hence the boxy future cars.

The change to curvaceous, streamlined car bodies was driven by stricter automobile fuel efficiency requirements, enacted by the U.S. government in response to the Arab Oil Embargoes of the 1970s. Carmakers found that one of the easiest ways to make cars more fuel efficient was to streamline their exteriors to reduce air resistance.

Since there’s no reason to think vehicle fuel efficiency standards will ever come down (if anything, they will rise), there’s also no reason to expect boxy, angular cars to return.

Just after I’d finished analyzing this car prediction, look who showed up.

**IMPORTANT NOTE I’M ADDING AT THE LAST MINUTE: On November 21, 2019, Elon Musk debuted Tesla’s “Cybertruck” at an event in Los Angeles, and the vehicle is a trapezoidal, sharp-angled curiosity that looks fit for the dark streets of Blade Runner. While I doubt it heralds a shift in car design, and it’s possible the Cybertruck could be redesigned between now and its final release date in 2021, I’d be remiss not to mention it here.

Therapeutic cloning will be a mature technology. There’s a scene in the film where two fugitive replicants confront and kill the man who designed their eyes in his genetics lab. It further establishes the fact that the replicants are made of organic parts that are manufactured in separate labs and then assembled. This technology is called “therapeutic cloning,” and today it is decades less advanced than Blade Runner predicted it would be.

Two replicants confronting the geneticist who designed their eyes.

We are unable to grow fully-functional human organs like eyes in labs, and can barely grow rudimentary human tissues using the same techniques. The field of regenerative medicine research was in fact dealt a serious blow recently, when a leading scientist and doctor Paolo Macchiarini was exposed as a fraud. Dr. Macchiarini gained worldwide fame for his technique of helping people with terminal trachea problems by removing tracheas from cadavers, replacing the dead host’s cells with stem cells from the intended recipient, and then transplanting the engineered trachea into the sick person. For a time, his work was touted as proof that therapeutic cloning was rapidly advancing, and that maybe Blade Runner levels of the technology would exist by 2019. Unfortunately, time revealed that Macchiarini had faked the results in his medical papers, and that most of his patients died soon after receiving their engineered tracheas.

The actual state-of-the-art in 2019 is lab-made bladders. Being merely an elastic bag, a bladder is much simpler than an eye.

Legitimate work in regenerative medicine is overwhelmingly confined to labs and involves animal experiments, and there are no signs of an impending breakthrough that will enable us to start making fully functional organs and tissues that can be surgically implanted in humans and expected to survive for non-trivial lengths of time. The best the field can muster at present is a few dozen procedures globally each year, in which a small amount of simple tissue, such as a bladder or skin graft, is made in the lab and implanted in a patient under the most stringent conditions. (Of note, only a small fraction of people with missing or non-functional bladders have received engineered bladders, and the preferred treatment is to do surgery [called a “urostomy”] so the person’s urine drains out of their abdomens through a hole and into an externally-worn plastic bag.) As noted in my Predictions blog entry, I don’t think therapeutic cloning will be a mature field until about 2100.

Advertisements will be everywhere. In Blade Runner, entire sides of buildings in L.A. have been turned into huge, glowing, live-action billboards advertising products. This prediction was right in spirit, but wrong in its specifics: Advertisements are indeed omnipresent, and the average person in Los Angeles is probably more exposed to ads in 2019 than they would have been in 1982. However, the ads are overwhelmingly conveyed through telecommunications and digital media (think of TV and radio commercials, internet popup ads, browser sidebar ads, and auto-play videos), and not through gigantic billboards. Partly, I think this is because huge video billboards would be too distracting–particularly if they also played audio–and would invite constant lawsuits from city dwellers who found them ruinous of open spaces and peace.

Which is worse: Huge video billboards or being constantly pummeled with spam emails, digital ads, and the knowledge that your personal internet data is being sold and traded without your control?

No one will turn on the lights. Blade Runner is a dark movie. No, I mean literally dark: Almost all of the scenes are set at night, and no one in the movie believes in turning on anything but dim lights. It may have been a bold, iconic look from a cinematography standpoint, but it’s not an accurate depiction of 2019. People do not prefer dimmer lights now, and in fact, nighttime artificial light exposure is higher than at any point in human history: satellites have confirmed that the amount of “light pollution” emanating from the Earth’s surface (mainly from street lights and exterior building lights) is greater than ever and still growing. Also, people now spend so much time staring into glowing screens (smartphones, computer monitors, TVs) that circadian rhythm disruption has become a public health problem.

If your light is so bright that it can be seen in space, then you’re wasting a lot of electricity.

Intriguingly, I don’t think this trend will continue forever, and I think it’s possible the world will someday be much darker than now. I intend to fully flesh out this idea in another blog entry, but basically, as machines get smarter and better, the need for nighttime illumination will drop. Autonomous cars will have night vision, so they won’t need bright headlights or bright streetlights to see the road. Streetlights will also be infused with “smart” technology, and will save energy by turning themselves off when no cars are around. And if intelligent machines replace humans (and/or if we evolve into a higher form), then everyone on Earth will have night vision as well, which will almost eliminate the need for all exterior lights.

Note that, in controlled environments, machines can already function in the dark or with only the dimmest of lights. This is called “lights-out manufacturing.” As machines get smarter and move from factories and labs to public spaces, they will bring this ability with them. My prediction merely seizes upon a proof of concept and expands upon it.

It will be possible to implant fake memories in people. Very early in a replicant’s life, he or she is implanted with fake memories. The process by which this is done is never revealed, but it is sophisticated enough to fill the subject’s mind with seeming decades of memories that are completely real to them. We lack the ability to do this, though psychological experiments have shown in principle that people can be tricked into slowly accepting false memories.

Since memories exist as physical arrangements of neurons in a person’s brain and as enduring patterns of electrochemical signaling within a brain, it should be possible in principle to alter a person’s brain in a way that implants a false memory in him or her, or any other discrete piece of knowledge or skill. However, this would require fantastically advanced technology (probably some combination of direct brain electrical stimulation, hypnosis, full-immersion virtual reality, drugs, and perhaps nanomachines) that we won’t have for at least 100 years. This is VERY far out there, along with being able to build humans from different body parts grown in different labs.

Computer monitors and TVs will be deep, and there will not be any thin displays. In one scene, we get a good look at a personal computer, and it appears to have an old-fashioned CRT monitor, and is almost a foot deep. Additionally, flat-panel TVs, computer monitors, laptops, or tablets and never seen in the film. This is a largely inaccurate depiction of 2019, as flat-panel screens are ubiquitous, and the average person owns several flat-screen devices that they interact with countless times per day.

Deckard sitting on his couch while looking at his computer screen. It looks like there might also be a second screen at the far right, facing away from him. Note that he doesn’t like turning on the lights.

I said the depiction was largely inaccurate because, even though CRT monitors and TVs are obsolete and haven’t been manufactured in ten years, millions of them are still in use in homes and businesses across the world, mainly among poor people and old people who lack the money or interest in upgrading. There’s even a subculture of younger people who prefer using old CRT TVs for playing video games because the picture looks better in some ways than it does on the best, modern OLED displays. In short, while it’s increasingly rare and unusual for people to have deep, CRT computer monitors in their homes, it is common enough that this scene from Blade Runner can be considered accurate in its depiction.

The median and mean lifespan of a CRT TV is 15 years, and almost none of them last more than 30 years. With that in mind, functional CRT monitors will not be in use by 2039, except among antique collectors. The Baby Boomers will be dead by then, and their kids will have thrown away any CRT screens they were clinging to.

People will talk with computers. Deckard’s apartment building has a controlled entry security feature: anyone who enters the elevator must speak his or her name, and the “voice print” must match with someone authorized to have access to the building, or else the elevator won’t go up. Also, in his apartment, Deckard uses voice commands to interface with his personal computer. Blade Runner correctly predicted that voice-user interfaces would be common in 2019, though it incorrectly envisioned how we would use them.

Electronic, controlled entry security technology in common areas of apartment buildings, like elevators and lobbies, are very common, but overwhelmingly involve using plastic cards and key fobs to unlock scanner-equipped doors. In fact, I’ve never seen a voice-unlocked door or elevator, and think most people would feel silly using one for whatever reason.

Smart speakers like the Amazon Echo are also very common and can only be interfaced with via speech. Modern smartphones and tablets can also be controlled with spoken commands, but it’s rare to see people doing this.

This brings up the valuable point that, though speech is an intuitive means of communication, we’ve found that older means of interface involving keyboards, mice, and reading words on a screen are actually better ways to interact with technology for most purposes, and they are not close to obsolescence (and might never be). An inherent problem with talking with a computer is you lose privacy since anyone within earshot knows what you’re doing. Also, while continuous speech recognition technology is now excellent, the error rates are still high enough to make it an aggravating way to input data into a machine compared to using buttons. Entering complex data into a computer, such as you would do for a computer programming task, is also much faster and easier with a keyboard, and anything involving graphical design or manipulation of digital objects on a screen is best done with a mouse or a stylus.

To understand, watch this clip of Deckard talking to his computer, and think about whether it would be easier or harder to do that image manipulation task using a mouse, with intuitive click-and-drag abilities to move around the image, and a trackball for zooming in and out: https://youtu.be/QkcU0gwZUdg

Deckard holding a photograph he found.

Hard copy photographs are still around. In that scene, Deckard does the image manipulation on a photograph that he found. He inserts it into a slot in his computer, and it scans it and shows the digital scan on his screen. While hard-copy photographs are still being made in 2019, they’re very uncommon, especially when compared to the number of photographs that were taken this year across the planet, but never transferred from digital format to a physical medium. I doubt that even 0.01% of the personal photographs ordinary people take are ever printed onto paper, and I doubt this will ever change.

Image scanners will be common. The computer’s ability to make a digital copy of a physical image of course means it has a built-in scanner. This proved a realistic prediction, as flatbed scanners with excellent image scan fidelity levels cost under $100. When Blade Runner was filmed, scanners were physically large, very expensive, made low-quality image conversions, and were almost unknown to the general public.

Cameras will take ultra high-resolution photos. The photo that Deckard analyzes is extremely detailed and has a very high pixel count, allowing him to use his computer to zoom in on small sections of it and to still see the images clearly. In particular, after zooming in on the round mirror hanging on the wall (upper right quadrant of the photo shown above), he spots an image of one of the replicants. While grainy, he can still make out her face and upper body.

It’s impossible to tell from the film sequence exactly how high-res the photo is, but today we have consumer-grade cameras that can take photos that are about as detailed. The Fujufilm XT30 costs $800 and is reasonably compact, putting it within the range of average-income people, and it takes very high quality 26.1 MP photos. One of its photos is shown above, and if you download the non-compressed version from the source website and open it in an imaging app, you’ll be able to zoom in on the rear left window of the car far enough to see the patterns of the decals and to read the words printed on them. (https://www.theverge.com/2019/4/12/18306026/fujifilm-xt30-camera-review-fuji-xt3-mirrorless)

Firearms will still be in use. The only handheld weapons we see in the film are handguns that use gunpowder to shoot out metal bullets. One is shown for only a split-second at the start of the movie when a replicant shoots a human, and the other is seen several times in Deckard’s hands. It’s big, bulky, looks like it shoots more powerful bullets than average, and has some glowing lights that seem to do nothing. In short, it’s nothing special, and probably isn’t any better than handguns that most Americans can easily buy for $500 today. Thus, the depiction the 2019’s state-of-the-art weaponry is accurate.

Deckard pointing his pistol.

And I do say “state-of-the-art” because, being an elite bounty hunter on an important mission to kill abnormally strong, dangerous people, Deckard has his choice of weapons, and it says a lot that he picks a regular gunpowder handgun instead of something exotic and stereotypically futuristic like a laser pistol. As noted in my reviews of The Terminator and Starship Troopers, we shouldn’t expect firearms to become obsolete for a very long time, and possibly never.

Video phone calls and pay phones will be common. There’s a scene where Deckard uses a public pay phone to make a video call to a love interest. This depiction of 2019 turned out to be half right and half wrong, but for the better: Pay phones have nearly disappeared because even poor people have cell phones (which are more convenient to use). Video call technology is mature and widespread, the calls can be made for free through apps like Skype and Google Hangouts, and even low-end smartphones can support them.

It’s surprising that video calls, long a staple of science fiction, became a reality during the 2010s with hardly anyone noticing and the world not changing in any major way. Also surprising is the fact that most people still prefer doing voice-only calls and texting, which is even more lacking in personal substance and emotional conveyance. Like talking with computers, using video calls to converse with other humans has proved more trouble than it’s worth in most cases.

Why flying cars never took off and probably never will

Flying cars have been a part of the popular imagination since the 1960s, maybe earlier.

Ah, flying cars, a staple of science fiction since The Jetsons, how I hate thee. Let me count the ways…

First, let’s define what we’re talking about: A “flying car” is a vehicle that can fly through the air like an aircraft AND ALSO drive on roads like an ordinary car. Thus, though it might take off and land vertically like a helicopter, a flying car is different from a helicopter because it can also move long distances on the ground.

In theory, flying cars would be more versatile than land-only cars and air-only aircraft, but their dual-role nature would impose design compromises that would make them far less efficient than either of the other two. For example, a flying car’s wings would be useless dead weight and bulk when the vehicle was driving on roads, and its wheels and transmission would be useless dead weight and would produce major drag when the vehicle was flying through. As a general rule, flying cars would be heavier, slower and less fuel efficient in the air compared to small aircraft, and more prone to breakdowns, less safe, and less fuel efficient on the ground compared to normal cars. 

The Jetsons aired in 1962, and popularized the idea that there would be flying cars in the future.

Without getting into any more detail, we can say that flying cars are a flawed concept, and there’s no reason why this shouldn’t have been obvious to engineers in the 1960s (or earlier) when The Jetsons aired and implanted in the popular consciousness the idea that flying cars would be common in the future. Unfortunately, none of those engineers spoke up (or maybe they did, but they were ignored), and flying cars went unchallenged. I think it’s unfortunate that so many works of science fiction featured flying cars, as they created an unattainable expectation in the minds of millions of people, which has led to predictable disappointment with the way things actually turned out and helped to prop up the false arguments of cynics and declinists. Peter Thiel’s famous quote aptly expresses this misguided disillusionment: “We wanted flying cars, instead we got 140 characters.”

I don’t like flying cars because their failure to appear by the deadlines set by works like Blade Runner is often held up as proof that technology is not improving and our lives aren’t getting better with time. As a student of history, I know that is badly wrong. I also don’t like them because they’re examples of bad futurism–They’re a future technology that sounds superficially cool, but that can also be shot full of holes by any reasonably smart person who spends a few minutes thinking about it critically, as I’ll now do in detail.

Using a thought experiment to build a hypothetical “flying car” from existing technology puts the problems in stark relief. Let’s start with a classic, reliable small plane–the two-seater Cessna 150–and mod it to be a flying car. The first problem we run into is that the wheels at the ends of their three landing gear aren’t connected to the engine by a transmission, meaning the pilot can’t make the wheels spin like he could in a car. Instead, pilots do ground taxiing by increasing the power to their engines, and the spinning of the propellers or jet blades pull the aircraft forward, just as they do when the plane is up in the air. Steering on the ground is done through differential braking of the wheels, and at higher ground speeds, through use of the rudder. While this is fine for traveling a few hundred meters from an airport hangar to a runway, it’s grossly unsuited for driving on roads with normal car traffic.

The iconic and frighteningly small Cessna 150.

We have to add a transmission that connects the Cessna’s engine to at least one of the plane’s wheels, and we also have to add some kind of mechanism to the engine that can disconnect it from the propeller when the craft is in “ground mode.” After all, driving down a residential street with a loud, spinning propeller at the front of your vehicle is obviously unsafe to pedestrians and would violate noise ordinances. We also need to add a feature that makes the wings fold up at the push of a button so the plane can be narrow enough to drive on standard roads. Installing the transmission, disconnector, and swivel mechanism adds weight, cost, and mechanical complexity to the Cessna.

Small planes can have folding wings for more compact storage. Our hypothetical flying car would need an automatic fold ability to make itself narrow enough to drive on roads.

So now, we’re ready. You put your modded Cessna 150 into “ground mode” and take it out for a spin. After a few minutes, you realize it’s the worst car you’ve ever driven. Your engine is literally five times louder than the cars around you and you’re constantly getting stares and seeing pedestrians around you covering their ears. Your “flying car” handles worse than a loaded dump truck (poor acceleration, wide turning radius, very mushy steering), struggles to reach highway speeds, and gets awful mileage. Finally, its small wheels and lack of a suspension system ensure every pothole and small rock on the road jolts your spine up into the base of your skull.

Though the vehicle folds up its wings at the push of a button to make itself narrow enough for you to drive on the road, it can’t shorten its 24 foot length, which dwarfs massive road-only vehicles like Chevy Suburbans (ONLY 18.5 feet long) and gives you a huge turning radius. But paradoxically, your Cessna 150 flying car doesn’t have any more interior space than an ultra-compact Smart Car: There are just two front seats and enough cargo space in the back for a full load of groceries. The ride is cramped and uncomfortable, you can’t use the flying car to transport any kind of big cargo, like a piece of lumber from Home Depot that you need for a simple home improvement project, and it can’t be an all-purpose family vehicle if there are more than three people in your household.

And worse yet, when you decide to forget that stressful experience by switching the Cessna to “air mode” and taking to the skies for a fun ride, you notice the plane is much slower, less maneuverable, and can’t travel as far on the same amount of fuel as before. All the mods you added to the plane to make it better at driving on roads have weighed it down, and it suffers in flight. Other small planes designed exclusively for air travel zip by you.

If this sounds like a sucky thought experiment so far, realize it actually gets worse. Your modded Cessna 150 would need more mods to meet car safety laws, like airbags, bumpers, and crumple zones, all of which add more weight, cost, and complexity. Granted, if this thought experiment is set in the distant future and car accidents have become very rare thanks to autonomous drive systems, it’s possible that some safety feature laws will be eased or eliminated. But not all of them, and for sure your Cessna would need more mods.

And as a person with discerning tastes, you’d doubtless want to install bigger wheels and a suspension system under your craft so every drive to the local store didn’t feel like mountain biking over a jagged rock trail. Which means–you got it–even more weight, cost and complexity.

After finally transforming your super-modded Cessna 150 so it drives as well as a low-quality car, to your horror, you discover that it has become so heavy and non-aerodynamic that it can barely take off into the air anymore! Maybe it can’t fly at all! Uh-oh! And now to fix THAT problem, you have to do a totally different set of mods…and you see where this is going.

Put simply, aircraft and land vehicles have totally different sets of role requirements, and making a “flying car” that can do both forces major design compromises, and it will never be as good in either role as specialized craft. This is true regardless of whether the flying car has wings like a small plane, or rotors like a helicopter.

Speaking of that, I forgot to mention that another limitation of your modded Cessna is that it will only be able to take off from long runways. Unless you are part of the ~2% of the population that lives on a large plot of flat land in the countryside, this means you’ll have to drive to an airport every time you want to go flying. The extra time spent driving your Cessna flying car to and from airports will be an inconvenience, and will actually make it faster to use ground driving mode to travel short- and even mid-distances.

But if your flying car were instead based on a two-seat Robinson R22 helicopter, you’d be able to get around that problem and take off from your suburban backyard, or from the roof of your apartment building, right?

Kinda…maybe…sometimes.

The Robinson R22–another classic

This brings us to two very important but overlooked problems with VTOL-based flying cars: noise and downdraft. Helicopters are very loud, and it would violate noise ordinances and cause people hearing damage if helicopters routinely landed and took off in their neighborhoods. Helicopters can be made quieter by giving them things like exotic main rotor blades, and cowlings around their tail rotors, but these design features are very expensive and only reduce noise levels by a few percent. Rumors that the U.S. military has top-secret “silent helicopters” are unsubstantiated, and I doubt it’s even possible to make helicopters that are “quiet enough” to land in your suburban backyard without jolting your neighbors out of bed. If big chunks of spinning metal are slicing through the air at hundreds of miles per hour, it will make a lot of noise no matter what. 

But even if very quiet helicopters could be made, the next show-stopping problem is downwash. A helicopter is able to go up because its main rotors blow air down at the ground with enough force to overcome the force that gravity is exerting on the helicopter. During takeoffs and landings, when helicopters are flying low to the ground, the downwash can be strong enough to blow over nearby lawn furniture, break tree branches off, blow off roof shingles, kick up big clouds of dust from the ground, and blow small pieces of debris like pebbles around at high speed. The attendant risk of injuries and property damage will ensure that it stays illegal for people to have personal helipads in their suburban backyards. 

We can calculate an R22’s downwash by using this equation: 

The data for the R22 can be found here: https://en.wikipedia.org/wiki/Robinson_R22

In spite of the fact that our hypothetical R22 is modded with a transmission going to its wheels, an engine-rotor disconnector mechanism, auto-folding rotors, air bags, and all kinds of other stuff to make it roadworthy, I’ll be really nice and say that thanks to use of futuristic weight-saving materials, its overall mass (including passenger[s]) is just 1,200 lbs. That yields a downwash of 22.5 ft/sec, but unfortunately, it’s actually worse than that:

“Keep in mind that this speed [derived from the equation] is at the rotor disk. As the column of air is forced down below the rotor, it constricts, much like molasses being poured out of a pitcher does. In doing so, it reaches its maximum velocity at 1.5 — 2 rotor diameters below the disc.”
https://www.rotorandwing.com/2011/11/29/calculating-rotor-downwash-velocity/

So our “R22 flying car” produces a downwash of 45 ft/sec, which is 30.6 mph. That’s not hurricane-force, but it’s strong enough to kick up clouds of dust, blow common objects over, and hurl pebble-sized debris into a nearby bystander’s eye with enough force to send him to the hospital. If the approach route to your backyard helipad requires you to fly low over someone else’s house or any sort of public space, then the clock will be ticking on someone suing you. So unless you have a very large yard that you’re willing to build a helipad in the middle of, forget it. While we can debate what the pace and direction of technological and scientific development will be in the future, there is no debate that people will continue getting more litigious and fussy with time. Someone will sue you because your flying car is too loud, or because it hurt them by blowing debris at them (even if the claim is a lie).

This helicopter’s downwash is evident by looking at the grass beneath it.
The dust cloud beneath this Harrier jet also reveals the power of its downwash. The Harrier doesn’t have a main rotor like a helicopter, but it still hovers the same way: by blowing vapor at the ground.

Let me insert an important caveat, which I first noted in my Starship Troopers movie review: The noise and downwash of VTOL flying cars are only problematic if we assume they’re to be used in a future world full of humans. If, on the other hand, we assume the future will be populated by machines and not humans, then noise and downdraft won’t be obstacles at all since machines won’t have finicky senses or frail bodies that can get hurt by little pieces of high-velocity debris. It might also be possible to reduce some safety features in aircraft intended for machines that have bodies that are more durable than ours. However, it’s also likely that machines will be very rational and won’t have the same problems we do planning their actions in advance, so from a resource usage standpoint, they would rarely use flying cars as it would be too wasteful a means of transportation. Traditional vehicles like boats, railcars, and big trucks will remain cheaper ways to transport cargo than aircraft.

And if you’re wondering whether we could avoid these problems by inventing some kind of anti-gravity or gravity-cancelling device that flying cars could use to go up and down with blowing air at the ground or needing long runways, realize that such technology is impossible because it violates the laws of science. Our understanding of how the force of gravity works provides no avenue for it to be controlled in such ways (and even if it were possible, it might require impossibly large amounts of energy). If your craft is heavier-than-air, and if you want it to do controlled flight, you either 1) need to give it wings and an engine so it can take advantage of lift, or 2) need to give it a downward-facing fan or rocket nozzle to blow vapor down hard enough to overpower gravity. Those are the only options.

Cars that can silently hover in the air without blasting some kind of vapor at the ground are impossible.

Finally, in “ground mode,” our “R22 flying car” would have the same inefficiencies and problems as the “Cessna 150 flying car,” such as poor performance and handling, excessive length but deficient interior space compared to ground-only vehicles, etc.

The British “Merlin” helicopter can fold its main rotor and its tail to reduce its overall length, but it is still quite long. An R22 with these features would still have a “folded up” length comparable to a full-size SUV, but less interior space than an ultra-compact car.

Another problem is that the standards for “airworthiness” are much more stringent than the standards for “roadworthiness,” so minor damage from something like backing your flying car into a concrete pillar in a parking garage, or having your side window broken by your neighbor’s kid throwing around a baseball in his yard will ground the vehicle until it is inspected and fixed. Flying cars would surely have advanced and extensive internal diagnostic systems to detect such problems, and they will refuse commands to take to the air if there were even a minuscule chance of in-flight mechanical failure. This means the autonomous drive systems would have to be almost totally perfect to ensure even the slightest accidents never happened. And even if that technology existed, you’d have no way to stop vandals or reckless people from disabling your flying car’s ability to fly by inflicting small amounts of damage on it. The availability of “flight mode” would not be reliable, and you’d always be at risk of getting stranded hundreds of miles from home after flying there and then suffering minor damage to the vehicle.

Bad weather will also keep flying cars grounded much of the time–just as is already the case for small aircraft–undercutting them as reliable means of daily transportation. Since piloting a small aircraft is very hard and dangerous, it’s unrealistic to expect a large fraction of the population to learn how to fly flying cars, so the vehicles will need to have advanced autopilot computers. For legal liability reasons, the computers would be programmed to fly very cautiously, and they would refuse to take off if there were even a small chance of hitting bad weather. Unless you are lucky enough to live in a part of the world with very mild, unchanging climate, this means your flying car will only be able to take to the air in fits and starts, preventing you from creating a daily lifestyle organized around the ability to fly from one place to another. This throws a monkey wrench into visions of a future where we all live on big estates in the countryside where land is cheap, and fly into the big city each day for work (also, why not just telework?).

Of course, even if you were assured of a safe landing, you probably wouldn’t want to fly a small aircraft through bad weather, since by virtue of their size, small planes and helicopters suffer worse turbulence than the big passenger planes most people fly on. Being flung around the inside of the cabin by every shifting gust of wind is upsetting for most people, and enduring that while also knowing your life is in the hands of a computer autopilot would be unbearable for a great many (this feeling of not being in control disproportionately frightens humans for complex psychological reasons). Most people can barely muster the courage to climb a ladder to clean their house gutters, let alone fly in a small aircraft. Fear of flying will be a big obstacle to flying cars, and an even bigger obstacle to flying motorcycles and personal jetpacks.

I’m still not done! Flying cars also make no sense for short-distance transportation, like moving around your own town or city. The extra time spent getting to cruising altitude and then landing would make it faster to just stay on the ground and use the roads. The fuel costs of vertical takeoffs and landings also would also be much too high to justify short-distance trips that could be done cheaper and (almost) as quickly with land-only vehicles. These problems both get worse if you assume lots of people in your town or city have flying cars, since that would lead to the equivalent of traffic jams in the sky, and you’d have to fly slower and hover while you waited for a helipad space to open at your destination.

Flying cars also wouldn’t make sense for long-distance transportation over intercontinental or even cross-continental distances, because their fuel tanks wouldn’t be big enough for the journey, and because taking a traditional passenger plane would be much cheaper and faster. Consider that the Boeing 787-900 at full 362-seat capacity gets 87 miles per gallon of fuel, per passenger (https://paullaherty.com/2012/05/25/boeing-737-vs-toyota-prius-this-might-surprise-you/). In comparison, a Cessna 150 gets about 44, and a Robinson R22 gets about 22 miles per gallon of fuel, per passenger. A Boeing 787-900 also flies at 560 mph while the Cessna 150 and R22 fly at 122 and 110 mph, respectively, so the big passenger plane will get you to your destination much faster.

Cessna 150 spec sheet from which I derived the 44 mpg-per-passenger figure.
R22 spec sheet from the Robinson website from which I derived the 22 mpg-per-passenger figure.

This leaves sporadic mid-range travel, which I’ll define as trips between 100 and 400 miles in length, as the one transit niche where it might make sense to use a flying car. But how many people need to frequently travel such distances? If you live in a metro area (including suburbs and exurbs), you’ll be able to satisfy the vast majority of your recreational and social needs without having to travel more than 100 miles from home. And as I established earlier, if you work far from home, it would be a much better idea to telework from your house instead of flying to and from your office building every day (and in any case, at random intervals, bad weather would block you from flying to work, so you couldn’t rely on it).

Flying cars would definitely make it easier to take vacations to the farther-flung parts of your geographic region. As a resident of greater Washington, DC, if I had a flying car, I would go to New York City and the beach more often each summer since both would be quick day trips, negating the need to stay overnight and pay high hotel rates. I would also explore southeastern Canada, and go to my favorite Appalachian hiking spots more, but all of this would only translate into a few extra weekend trips per year. Like most adults, I have responsibilities that often keep me pinned down, and sometimes I’m just too lazy to leave town even when I technically could. If I had a flying car, most of the time I’d be using it in “ground mode” for short-distance trips, and would be griping over its poor performance, uncomfortable ride, and limited utility. I’d probably be better off saving money by just sticking to a ground-only car and accepting a reduced ability to go to New York and the beach.

The counterargument, which is “Just keep your normal car for everyday road travel, and buy a flying car for sporadic regional travel,” makes me realize that there is a different transit model that is better than the “one flying car per person” model shown in many sci-fi movies: What if we don’t build any flying cars at all, and instead build a dense network of airstrips and helipads that people could quickly and cheaply travel through using autonomous, rentable, “air-only” aircraft? What if we paired this with an autonomous carsharing model that would quickly move people to and from those helipads and airstrips? Such an arrangement would provide all the advantages of the “one flying car per person” model without any of the downsides.

For trips in and around your metro area, you would rent self-driving Uber cars that would stay on the ground. Since most (or all) of the other cars on the roads would also be autonomous, they would precisely coordinate traffic flows, meaning there would almost never be accidents or congestion. Cars would traverse the roads much faster than they do today. Additionally, since these vehicles would be designed solely for ground use, they would be optimized for that role and would be safe, fuel efficient, and comfortable inside.

If your job were far from your home, you would telework by using technologies that already exist, or, if that were inadequate for some reason, by using virtual reality technologies that will exist in the near future. The amount of energy required to power your teleworking equipment would be much less than what would be required to fly to your work site each day in a small aircraft or flying car, and if you teleworked, you wouldn’t lose any time at all commuting.

On the rare occasions when you wanted to go somewhere outside your metro area but within 400 miles–let’s say to meet with a very important client at the office building you normally telework to, or to take a weekend trip to the beach or a different city–you would have one of the self-driving Uber cars you normally use take you to the nearest airstrip or helipad. Assume this scenario is happening a few decades from now, and your country has invested money during the interim increasing the number and density of airstrips and helipads, so most of your citizens live within a 20-minute drive of one. They are typically sited just outside of towns or in industrial areas so no one is close enough to hear the sounds of the aircraft landing and taking off. It’s also very common for large buildings to have rooftop helipads.

Your self-driving Uber car takes you to the local helipad or airstrip, where you exit and walk a short distance to a waiting self-driving Uber helicopter or plane. Since the aircraft is a two-seater, and either you’re traveling alone or with only one other person, you don’t have to waste time going through a security check: You can’t take over the aircraft in flight since there are no manual controls and can’t do significant damage by blowing it up. The small aircraft flies you to the airstrip or helipad closest to your destination, and when you disembark, there is a second self-driving Uber car waiting for you nearby. Moreover, since the small aircraft is designed only for flight, it is totally optimized for that role, and is much more fuel efficient than a dual-role “flying car” would be.

Alternatively, we might use high-speed, autonomous Uber cars for 100 – 400 mile trips. The cars would be very streamlined and low to the ground for optimal performance at, say 100 mph. They wouldn’t be much slower than small aircraft for many journeys, and would be safer and possibly cheaper for passengers. If all of the cars on the roads were driven by machines networked to each other, then high-speed cars like this could safely share the roads with slower cars.

Cars designed to spend most of their time driving at high speeds could ferry people over mid-distances.

And finally, if you needed to quickly travel more than 400 miles, you would have a self-driving Uber car take you to the nearest big airport, where you’d disembark and go through the same process that exists today to board a large passenger plane.

In conclusion, I think flying cars are a flawed concept; it’s unfortunate that they’ve appeared so much in science fiction and created an unrealistic vision of the future for many people; and a transit model based around autonomous small aircraft, networks of helipads and small airstrips near population centers, and autonomous road-only vehicles ferrying people to and from the helipads and airstrips would be better than giving everyone a flying car. Moreover, I think the speed and efficiency of ground transportation could be greatly improved by autonomous cars, negating the need for flying cars to move people around cities that have bad road congestion today, and also opening the door to rapid ground transit across mid-distances. While flying cars and small aircraft can be redesigned to reduce their noise signatures (for instance, by using electric engines and installing helicopter tail rotor cowlings), it’s probably impossible to make them quiet enough to land and takeoff in densely populated areas without disturbing people to the point that they take legal action. I also think flying cars would be more feasible in world full of intelligent robots but no humans, but still wouldn’t replace older modes of transit.

The logical endpoint of various weapon trends is guided bullets. It’s hard to build them since the G-forces imparted on the projectile as it was fired are so strong they could crush the computers, sensors and steering fins inside of it. Note that guided bullets only give you an advantage if you know where your enemy is, and for many reasons, your enemy will by default try to hide from you. This means that even in the distant future, it will be useful to saturate areas of the battlezone with “dumb” projectiles like unguided bullets and bomb shrapnel to hit any bad guys that could be concealed there.

The USAF has selected the Boeing “T-X” to be its new training jet. It will replace the T-38, which first flew in 1959. Given the longevity of modern warplanes, the T-X should stay in service until at least the 2060s, by which time fighter and bomber planes might be automated, rendering human pilots obsolete. Thus, the T-X could be the last, or at best the second-to-last, trainer aircraft that the USAF ever makes. AIs won’t need to spend time in a simplified practice plane to learn how to fly. They will just be created in software labs and uploaded directly into frontline combat planes. Someday, the very notion of a “trainer aircraft” will be obsolete.

A new device called the “Everlast” notebook saves writings and drawings as data files. What kills it is the fact that you have to take photos of what you’ve written on the pages to save them digitally. The pages themselves should be able to detect what the user has written on them, and to upload it to their remote storage drive.

Prediction: Within 20 years, books and computer tablets will merge into a single type of device that could be thought of as a “digital book.” It will be a book with several hundred pages made of thin, flexible digital displays (perhaps using ultra-energy efficient e-ink) instead of paper. At the tap of a button, the text on all of the pages will instantly change to display whichever book the user wanted to read at that moment. They could also be used as notebooks in which the user could hand write or draw things with a stylus, which would then be saved as image or text files. The devices will fuse the tactile appeal of old-fashioned books with the content flexibility of tablet computers.

We don’t know if there’s enough CO2 sequestered in Mars’ soil to create an atmosphere via terraforming machines. I think that, by the time we have the ability to send large numbers of people to Mars, intelligent machines will probably dominate Earth and cancel any senseless plans to send more than token numbers of resource-hogging meatbags like us there. Multi trillion dollar plans to terraform Mars will also be considered too wasteful to proceed.

A simple explanation of how the Asteroid Belt, Kuiper Belt and Oort Cloud are different.
http://ryanmarciniak.com/archives/390

‘The total mass of the asteroid belt is estimated to be between 2.8×10^21 and 3.2×10^21 kilograms, which is just 4% of the mass of the Moon.’

That sounds small until you think about this: A Ford-class aircraft carrier is 9.1 million (9.1×10^6) kilograms. A space warship ten times that size–which is in the same ballpark as a Star Destroyer–would thus be 9.1×10^7 kg. If we had space factories and converted just ONE PERCENT of the asteroid belt’s mass (I used the lower of the two estimates) into space warships, we could build 30.7 QUADRILLION ships.

The U.S. and Britain only became allies around 1900, when Germany’s rise forced Britain to nearly withdraw from the Americas to secure its rear flank and shuffle its limited military resources to Europe.  The U.S. also correctly calculated that it could pressure Britain to the bargaining table if it built its own navy up enough to give it regional superiority to the Royal Navy in the Caribbean. Similarly, if the Chinese achieve regional superiority over the Americans in the South China Sea, it could make U.S. forces peacefully (but begrudgingly) cede control.

Fields medalist Alain Connes praises the defunct Soviet math academies, and of the general merits of allowing smart people to pursue pure knowledge instead of being pressured to use their talents to make money. If machines make human labor obsolete and everyone is put on welfare–er, a UBI–will people follow their passions and cultivate useful, inborn talents? Or at that point in the future, will human math geniuses just run into more frustration since machines would also be superior at pure math?

Autonomous cars would make traffic lights obsolete since the vehicles would wirelessly coordinate with each other to avoid collisions. Perpendicular streams of car traffic could flow through each other’s gaps at road intersections with the precision of Blue Angels stunt pilots. Eliminating stop lights would improve the flow and rhythm of traffic,  reducing jams. I also predict that this ability to coordinate as a swarm will allow for dynamic lane reversals according to acute changes in traffic flow. For example, imagine there’s a city where everyone works, a suburb where everyone lives, and an eight-lane highway connecting the two. Every morning, the four lanes leading into the city are clogged with cars because all the people are trying to get in to their workplaces and the four lanes leading out of the city are empty, and every evening the reverse is true. If all the people have autonomous cars, only a four-lane, one-way highway would be needed since the cars would all switch directions without danger of head-on collisions twice a day to match the changing needs of the flow of people.

The more interesting and much more plausible future technology the article touches on is automated inventories of all items in your home. Once you have enough cameras in your home, and perhaps a robot butler, they’d set about identifying every object in every room to create a list. (Monitoring of refrigerator contents and automated ordering of replacement foods to replace those verging on exhaustion or spoilage will be another aspect of this.) The frequency with which you used the objects would also be observed, and your machines would encourage you to get rid of things you never used, like your old set of skis. They’ll make it easy by putting ads on eBay and scheduling times for buyers to pick them up. You’ll just have to push the “OK” button. Physical goods will be allocated across the population more efficiently as a result, and prices for things will go down once billions of objects collecting dust in garages and attics enter the market.

Automated personal inventories will also show us how infrequently we use possessions we consider “essential,” like tools (e.g. – you only use your rake two days per year, each autumn), which will probably give rise to “libraries of things” instead of personal ownership. (This is simply an extension of the same logic supporting the idea that Uber-style ridesharing will replace personal car ownership.) When you think about it, it really is kind of crazy to spend money on something that sits idle in your house 99.99% of the time.

The first Designer Baby could be born within ten years, but it will be decades longer before even 5% of babies born each year are engineered.

Chinese geneticists used CRISPR to replace disease-causing alleles in human zygotes, without side effects to other parts of the genomes. The zygotes could have been implanted in women through IVF, and if carried to term, the resulting children would have been the first genetically engineered humans in history. I predict the milestone will happen by 2039, and perhaps as soon as 2028.

Arnold Schwarzenegger’s admission that his muscled physique elicited polarized reactions from women (half thought it was hot, half thought it was repulsive) have implications for human genetic engineering. People would use it to make kids that were leaner and stronger, but due to aesthetic concerns, few would push it to the very extreme of what is possible.

Anyone interested in engineering their kid to have a specific eye color should note that there are such things as surgically implanted fake irises that do the same thing. I note that most of the YouTube videos about this (the “Bright Ocular” implant) have titles like “bright ocular removal,” “never get bright ocular” or “bright ocular made me blind.” Maybe iris implants will be better by the time human genetic engineering is widespread.

“If AI rationally allocates resources through big data analysis, and if robust feedback loops can supplant the imperfections of “the invisible hand” while fairly sharing the vast wealth it creates, a planned economy that actually works could at last be achievable.”
This same thought occurred to me a few years ago. Communists shouldn’t get too excited though, since the same AI-powered mass surveillance system would also keenly understand the abilities of each human and could track whether they put in an honest day’s work or not, which would in turn affect the AI’s decisions about how “fair shares” of the day’s wealth should be allocated.

If you’re only counting animals that might have consciousness and can probably feel pain, daily births are in the billions per day. Since those species’ populations are mostly steady-state (neither growing nor declining overall), then the same number of deaths must happen each day. Many of those deaths are agonizing because they owe to untreated injuries, disease, or slaughter at the hands of unskilled humans. There’s a fringe coalition of transhumanists, altruists, and animal rights advocates who think it is humanity’s ultimate mission to use technology to end this cycle of suffering, possibly by capturing all wild animals and putting them in something like The Matrix. All humans would also go vegetarian or switch to lab-grown meats.

‘The Summit’s theoretical peak speed is 200 petaflops, or 200,000 teraflops. To put that in human terms, approximately 6.3 billion people would all have to make a calculation at the same time, every second, for an entire year, to match what Summit can do in just one second. ‘
That is probably not true. We don’t know how much computation the human brain does, but the best guesses converge on the “tens of petaflops” realm, plus or minus one order of magnitude. So what this milestone really means is that, for $400-600 million, we can now build a supercomputer with the same raw processing power as 1-10 human brains. That sounds pretty snicker-worthy until you remember the cost-performance of supercomputers improves by an order of magnitude every 5-7 years. So using a conservative extrapolation, a supercomputer with the same power as 1-10 human brains should cost single-digit millions of dollars by 2033, putting them within reach of midsized businesses and second-tier college Computer Science departments. Big entities like militaries, spy agencies and Google will collectively have tens or hundreds of thousands of them. If we haven’t built an artificial general intelligence (AGI) by 2040, it won’t be thanks to deficient or costly computer hardware. It will be because we don’t know how to properly arrange the hardware to support intelligent thought and because of a failure to develop the software of intelligence.

Assuming a constant 3% inflation rate, $1 million in the year 2120 will only be worth $50,000 in today’s money. Being a “millionaire” in the future will be meaningless, and the title will probably fall out of use. (Similarly, it wasn’t long ago that having a $100,000 income was a huge deal.) But given that central banks support price inflation because it’s a sneaky way of cutting wages without making human workers mad, will inflation stop once machines take over the economy?

An ocean buoy detected a 78 foot high wave south of New Zealand, making it the largest wave ever recorded in the Southern Hemisphere. As the number and density of automated sensors like buoys, weather stations, and drones grow, so will data and film footage of extraordinarily rare occurrences and life forms. In 20 years, you’ll be able to ask your computer to “Show me everything weird that happened today” and spend the next several hours watching video clips from around the world, including places devoid of humans.

“Ocado” is a British grocery store chain that has no brick-and-mortar retail stores and only does home deliveries. Their food warehouses, where groceries are stored and packaged, are heavily automated and use hundreds of robots.

A fascinating piece that highlights some of the less-obvious ways autonomous vehicles will change the world.
https://arstechnica.com/cars/2018/05/self-driving-technology-is-going-to-change-a-lot-more-than-cars/

It will also probably be easy to program autonomous vehicles to drive in ways that use as little fuel as possible. Many human truck drivers have a hard time keeping up these habits because they require near-constant focus and patience. Moreover, since machines don’t need to sleep, autonomous trucks could structure their routes in such a way that they were mostly on the roads during non-peak hours, like the middle of the night, meaning fewer traffic jams for everybody and less wasted gas.

One of the NYT’s auto experts thinks gas-powered cars will be obsoleted by fast-recharging electric cars within five years, and sales of both will sharply shift to reflect this. Without giving a deadline for autonomous cars, he drops a lot of hints it will take substantially longer than five years to become mature and ubiquitous.

“[Intelligence] is a spectrum of abilities since there are many different goals you can have, so it makes no sense to quantify something’s intelligence by just one number [like an IQ score]. To see how ridiculous that would be, just imagine if I told you that athletic ability could be quantified by a single number, the ‘Athletic Quotient,” and whatever athlete had the highest ‘AQ’ would win all the gold medals in the Olympics.”

Here’s a supposedly genuine military report about the 2004 encounter between a U.S. Navy F/A-18 and a UFO off the coast of San Diego. The sighting was first described in a December 2017 New York Times article. The report deduces that the UFO could change altitude at ballistic missile speeds, was nearly invisible to radar, and might have had a cloaking ability on the visible light spectrum.

Between new plane purchases and upgrades of existing planes, the U.S. Navy plans to have at least 650 “Block 3” Super Hornet F/A-18E’s and F’s by 2025. They’re better than the current “Block 2” Super Hornets in every way.
http://www.thedrive.com/the-war-zone/21045/here-is-boeings-master-plan-for-the-f-a-18e-f-super-hornets-future

And in classic fashion, the Navy is dumping its worn-out, excess F/A-18C and D Hornets (note the lack of “Super”) on the Marine Corps. The Navy has 270 of these older fighter planes and will give the Marines 136 of them, mostly to be cannibalized for spare parts. The Navy’s final 134 Hornets will probably be transferred in the future as it gets more Super Hornets and F-35C’s.

In 1872, English writer Samuel Butler published the book Erehwon. In it, the main character visits a futuristic, closed society that banned machines because they were improving too fast and people feared they would become smarter than humans and take over. Butler was inspired by Darwin’s Theory of Evolution and by the rapid industrialization he saw in England over his lifetime. It’s the earliest example of the the “robot uprising” trope I’ve seen.

A few bummer remarks about the state of artificial intelligence. FIRST: ‘The current ways of trying to represent the nervous system…[are little better than] what we had 50 years ago.’  –Marvin Minsky, 2013
https://youtu.be/3PdxQbOvAlI

SECOND: ‘Over the next 30 years, we’re not going to see Commander Data…there is an A.I. bubble right now and people are making a fundamental error on estimating how good A.I. is going to be [and] how quickly.’ –Rodney Brooks, 2017
https://youtu.be/ig1qaqyMIXc

THIRD: ‘I suspect that [building the first true A.I.] means getting rid of back-propagation…I don’t think [back-propagation is] how the brain works.’ –Geoffrey Hinton (helped invent back-propagation in 1986), 2017

FOURTH: ‘We’re very far from having machines that can learn the most basic things about the world in the way humans and animals can do. Like, yes, in particular areas machines have superhuman performance, but in terms of general intelligence we’re not even close to a rat.’ –Yann LeCun, 2017
