Apollo had two reentry tests in Project Fire and two more tests of the actual capsule. This was the first test of Orion.

"Built to last X years" generally means a certain probability of everything, or nearly everything, working well for that long. They had very little idea what conditions the Voyagers would encounter, so that was a pretty fuzzy number. Even knowing much more, space missions still almost always outperform their "built to last" times, usually by many multiples.

Refrigerators in the 1940s were several times less effiicient, not "a little bit" and cost several times more than a refrigerator today, for a given volume.

The F16 is unstable in pitch at transonic and supersonic speeds, so unless you're flying slow you better eject quick or you probably won't be able to.

You can go find AI source code in any number of places, or very detailed descriptions of how modern AI works on hundreds of thousands of websites, books, courses, etc.

Modern AI systems learn from examples. That's where the "learning" in "machine learning" comes from. They are not programmed with every case, as with regular programs.

Certain classes of AI models called generative models can "hallucinate." That's in no way "proof" or any indication at all of the quality of their software. They are designed to be able to learn to create novel output. "Hallucination" is the point.

There are always trolls with mod points. People maintain multiple sock puppet accounts so they always have mod points.

Getting modded troll means you pissed off an asshole. Congrats.

Most modern ABS systems (I think all new cars) do work independently for each wheel. No, ABS doesn't exchange stopping distance for preventing skidding, it provides maximum braking force.

Were you the guy skipping highschool physics so he could go screech his tires out in the parking lot?

You don't want the wheels to stop (except at the end). The coefficient of sliding friction (i.e. locking the wheels) is *lower* than the coefficient of rolling friction. The best braking happens when the brakes are applying the maximum possible force without causing the wheels to slip on the road. ABS systems are designed to ride that line. That also means you can steer, but it's the least steering control you can have, except for locked wheels.

It's nowhere near as impressive as Moore's law, but it has been reliably trudging along.

$/kWh has had a halving time of about 3-4 years over the last decade, compared to the Moore's law heyday with a doubling time of about 1.5 years. It's not as fast, but it's exponential, pretty close, and damn impressive.

Yes, it's popular to put the blame somewhere else. It's the gubmint not me! It's a democracy. It is exactly the average citizen who is borrowing the money, and it is that average citizen (or their kids) who is going to get screwed by it.

The average citizen is also at record private debt levels, BTW.

This is Chang'e 6. Want to guess what Chang'e 5 did?

He's a legacy. The only way you can be more "global elite" than a multi-billionaire New York real estate mogul denounced for profiteering by Eisenhower is to be that guy's playboy son.

I was curious, so I looked it up. The paper is Oonincx et al.

So the global elite is this guy:

To be fair, the US is many times more dangerous than pretty much anywhere in Europe:

To be realistic, major reasons for that are probably as you indicated (see first link).

An enormous amount of medicine is placebo effect. That's why it still works even when the actual treatment is completely random. Physicians are trained to project confidence because it improves outcomes. Up until relatively recent times it was about the only thing that improved outcomes.

The combination of a human whose job it is to both project confidence and make you feel better, plus accurate diagnostics and treatment of the underlying problem will be unbeatable.
