And yet, the billionaires seem to have no problem converting that "guessed future wealth" into super yachts, private jets and political influence.

I dare say of we could git revert people after surgery we'd be a lot more relaxed about both undergoing it and letting people do it with less qualifications.

its pretty obvious why that gets sidestepped isnt it? There are multiple companies trying to go public with trillion dollar valuations on the premise that AI will change everything, it would be mad if they weren't spending hundreds of millions to billions in shaping public opinion that everything can be solved with AI.

I mean, I lead an initiative to move numerically heavy microservices from c# to numerical python in my previous job (that was initially a windows shop but absorbed a linux based r&d company) because c# was so limiting. But details on that don't really fit into a HN comment.

Crap is probably unfair, but they are incredibly limited for numerical work compared to python or c++

China generates more electricity from coal than from all renewables put together (49.7% per https://oilprice.com/Latest-Energy-News/World-News/Solar-Ove...).

They have more installed renewable capacity than coal, but renewables have low capacity factors, solar is less than 50% by definition. The renewable share is growing fairly rapidly, but it is by now means almost entirely renewable.

Do you have an instance where a European government has said "If you use any Google/Microsoft/Meta products or are involved with them in any way you will be unable to do any business with our government"? Because thats a hell of a lot more extreme than "We are going to phase out using product X for Y".

It's possible, but it seems more likely that the first tests would have shown "weird timing errors we couldnt diagnose" and then the project never got a follow up.

According to wiki, Tanzania has over 100 languages, including 15 with 1 million or more speakers. I can see language studies being useful somewhere.

The x-rays aren't just emitted in a single moment, they are the result of the initial core heating up to millions of degrees, so the light they emit just as a result of being hot is in the x-ray and lasts for some amount of time. This is long enough to generate the ionised air which continues to expand and absorb more x-rays until the initial core cools down somewhat. At that point you have a large amount of incredibly hot, incredibly high pressure plasma which then expands and causes the shockwave.

Heat alone is not insufficient, the heat generated is so intense that is turns the surrounding air into a plasma which then absorbs the x-rays emitted creating a stupendous over-pressure in the air which drives the shockwave.

Reactors don't explode because the amount of heat then generate is carefully monitored and matched the the rate at which that heat can be pulled from the reactor and converted into work.

The moon has an orbital velocity of ~1km/s, an M777 howitzer has a muzzle velocity of ~0.8km/s

There is no irony there, both statements are equally supported: not at all.
