In spite of Russia’s high losses in Ukraine and the related degradation in the quality of their replacement troops (most new recruits are in their 40s), the country has enough men to continue the war indefinitely.

It will take Russia about ten years to rebuild its military to pre-2022 strength levels, but its force composition will be different thanks to lessons learned in Ukraine.

Here’s a good video of a Russian tank being destroyed.

The first suicide drone hit is directly on the engine, which is at the rear right under where the trunk of a car would be. Though that didn’t destroy the tank and probably killed no one, it caused fatal damage to the engine, forcing the vehicle to slow down and stop. The crewmen and the infantry clinging to the tank know they have a big problem, so they all get out and run.

The second hit is to the front of the tank, and is done with a guided suicide drone that I bet has an armor-penetrating explosive attached to it. They were clearly aiming for the open hatch, but even if they missed, the attack was still successful. The explosion sends a jet of molten metal into the tank’s interior. Just two seconds after that first blast, the molten metal ignites the ammunition stored inside the tank and there’s a secondary explosion (big puff of smoke and sheets of flames) coming out of the barrel and other open hatches.

China’s new stealth fighter is designed to destroy U.S. AWACS planes, aircraft carriers, and bases with ultra long-range missiles (can hit targets 250 miles away). It is unsuited for dogfighting due to lack of maneuverability.

The new U.S. Secretary of Defense Pete Hegseth gave a pivotal address to America’s European allies in which he declared China was America’s primary threat, so Europe would have to shoulder more of its defense against Russia. He also said the restoration of Ukraine’s pre-2022 borders was an unattainable goal and that the U.S. would never send troops to defend Ukraine or allow Ukraine into NATO. This is a major win for Putin and represents a sharp break in outlook between Biden and Trump.

A factory near Philadelphia that you’ve never heard of had an outsized role in the U.S. aerospace parts supply chain. It just burned down, creating huge problems for aircraft companies.

I don’t claim to understand most of this essay, but it provides a good example of how pure math research can unexpectedly solve real-world problems.

One argument for continuing to invest in building better AIs even after they’ve passed the point of being able to satisfy all human needs is that better AIs will be able to explore more of the unbounded space of mathematics, which could lead to many unexpected benefits.

I think war gaming/making and economic modeling are two other areas where the gains from better AI will never top out. Both deal with systems that are so complex and random that perfect modeling will never be possible, so you’ll always gain an advantage from that nth bit of extra compute you have over your competitors.

Here’s a pretty incredible essay by a futurist titled “A History of the Future, 2025-2040.” It mainly focuses on the future of AI and the effects on humans, the economy, and geopolitics.

I predicted something like this would happen. Someday, storing and preserving the totality of useful knowledge produced by humans will be trivial.

‘The crystal containing the human genome has been stored in the oldest salt mine in the world, alongside the Memory of Mankind Archive. “Over time, the salt mine will naturally close as the mountain shifts, providing a stable and secure environment for the crystal. Since salt is soft, it will not damage the crystal, ensuring that it remains safe for millions of years until it is discovered by future civilizations.’

Trump gave his own explanation for the recent UFO sightings in the American Midatlantic: “After research and study, the drones that were flying over New Jersey in large numbers were authorized to be flown by the FAA for research and various other reasons,” Leavitt said, reading Trump’s dictation at her first briefing.

“Many of these drones were also hobbyists, recreational and private individuals that enjoy flying drones. In time, it got worse due to curiosity. This was not the enemy.”

The chemical ingredients for life are common in space. Also: ‘And the completely racemic character of those amino acids argues in two directions: that there is not some physics-based reason for one enantiomer to be favored over another in the absence of life, and in the other direction, that life on Earth was not seeded by falls of such enantiomerically enriched material to give us the patterns we see today. This is still far from a settled question, but these results are going to be hard to explain away.’

Musings 8

Wearable and nearby personal technologies that continuously monitor your health won’t just be able to save you during medical emergencies–they’ll be able to diagnose problems at their early stages, allowing you to seek treatment. Dealing with health issues early on is always more effective, cheaper, and less stressful than waiting until late. In so many small ways, human welfare will benefit from gadgets like smartwatches and robot servants that know what to look for in you.

Ultimately, neuroscience and cybernetics will let us switch our emotions on and off at will. While this would be an enormous boon to human wellbeing since it would let people experience prolonged bliss for nothing, it would also let us block out negative emotions, robbing us of a fundamental aspect of human existence. For instance, if your child died and you could click a button to banish the resulting heartache and obsessive thinking, you’d be committing a grave injustice. My big fear about that kind of technology is that it will lead to the near-total atomization of the human race, where indulging in various mental states and interacting with AI’s customized for you will be so much better than dealing with real humans that you won’t bother to at all.

As advanced brain cybernetics become common and humans gain the ability to share thoughts and sensations with each other, we’ll become more aware of how variations in brain structure, genetics, and other individual factors affect subjective experience. A baby eating a strawberry for the first time in its life will feel it more profoundly than an old man eating one for the millionth time. Eating any kind of food is probably more pleasurable for chronically obese people.

This means that there will not be a single “what a strawberry tastes like” file on the future internet for people to download into their minds; there will be many versions of it representing the various ways humans experience it. Knowledge of these (largely) genetically-rooted variations in acuteness and perception could lead some people to genetically engineer themselves to be capable of higher degrees of pleasure or unique types of pleasure. We might discover there are types of and heights of pleasure that Homo sapiens like us are too limited to experience. Multiple generations of evolutionary pressure towards this goal would produce “humans” who would be as alien as those optimized for superintelligence.

The first humanoid robot butlers will probably cost around $10,000. For the people unwilling to pay that much, I’m sure there will be cheaper deals allowing them to rent the robots for short periods of time each week. Once the robots get advanced enough, they will be able to fix themselves and each other, so they will take decades to wear out like home appliances and cars do. This longevity will boost their population growth rate, and eventually they will be so numerous that a secondhand one will be cheap enough for even poor people to buy.

It’s possible there’s an “equation for intelligence,” but that it’s too complex for the human mind to understand. By the same token, right now there are many, well-documented math proofs that you couldn’t understand even if you spent years studying the requisite math courses. You’d hit your IQ ceiling before you achieved the necessary foundation of knowledge.
