Life expectancy and death rate are not the same thing. The US has a younger population than, e.g. Spain, so it has a lower death rate (this year at least) despite also have a lower life expectancy.

Valve, no. The Internet, yes.

This isn't e-ink, but it's not actually completely different, and this guy tells you exactly how to do it:

Sure.

  They haven't released the source files yet but it's not exactly rocket science to put one together. E-ink screens are readily available, as are microcontrollers.

SpaceX made $75 billion actual real dollars. It's in the bank.

Sure, the individual VCs aren't allowed to take their actual cash out of the company until August 6. Want to bet the datacenter hype keeps going until at least then?

Elon Musk, or whoever manages him, already learned not to post speculative tweets about his companies followed up shortly later by "just jokes lol".

It's not great, but I don't think that's the least practical part of it. Reasonable people have done the math and you can almost make it work just by making the radiators the same size as, and putting them on the back of, the solar panels. Starlink satellites already generate and dissipate a kilowatt plus.

The impractical part is that the whole thing is going to deorbit and burn up after five years. Sure, maybe you don't want the five year old GPUs, but replacing the panels and radiators every five years is going to be more expensive than building twice as much on the ground.

Conspiracy theories are silly, and unnecessary.

Remember when Elon ruminated about hyperloop and everyone went nuts? Well, this time he ruminated about space datacentres. Oh, and SpaceX investors cashed out for ~$85 billion.

It is LEO.

Size is not free. Besides having to get the thing up there, which might come down to merely very expensive, there's drag in low Earth orbit, and the bigger the surface area of your satellite the more propulsion you need to keep it up there. The life of Starlink satellites is primarily limited by their propellant.

Even if you ignore launch costs entirely, is it cheaper to put your datacentre in space and replace it and your power plant every few years, or put it in a nice desert or on a floating island somewhere instead? Oh, and you have to engineer it to be completely maintenance free for the first option too.

What's the downside? SpaceX stock got pumped for their IPO. The money is made. As long as the hype keeps going they can raise more any time they want, or Elon could sell some of his shares. If it turns out to be unworkable, SpaceX (and subsidiaries) are back where they started.

There aren't really any unsolved engineering problems. SpaceX can absolutely put a rack of nvidia GPUs into low orbit. We could have done that in the 70s. The argument is whether it's economical or not.

Which is cheaper, putting a thousand square metres of solar panels, a rack of GPUs, a vacuum cooling system and propulsion in low orbit and incinerating and replacing it all every few years, or the panels, GPUs and a convective radiator that is ~50x more efficient on the ground and runs for twenty plus?

If I put some bricks or concrete blocks in a vacant lot and they assembled themselves into a house you'd think that was pretty cool.

I didn't say they didn't. Those missiles were very effective. Much more effective than ten times as many drones would have been.

Both missiles and drones are of limited use when you're not willing to send infantry to take and hold territory. Cheap light drones much more so than Tomahawks and GBU-57s.

The US didn't fail in the Iran war due to a lack of offensive air power, and its offensive air power definitely wouldn't have been improved by packing the Bush, Lincoln and the Burkes with cheap drones. It failed because it was a half assed effort organized by clowns who apparently don't know any military history and decdied to disregard all their advisors who do.

You can theoretically win a war with air strikes alone but it depends entirely on your enemy. If they fail to surrender then you lose, and there's a strong incentive to dig in when some foreign invader starts dropping bombs on you. That's why no real war has ever been won that way.

Using projected military power in general has always been hazardous. It's expensive, unpopular, and depends on either a quick victory or local allies, preferably both, or it will fail. "Local allies" are part of the soft power that Hegseth is so disdainful of, and the US has lately been lighting on fire just to watch the pretty flames.

Datacentres are coveted by lots of local governments. Lots of construction jobs, high paying jobs in operation and maintenance, no on-site pollution. It's like tourism without the tourists.

The locality in this story, along with the state of Virginia, offer a lot of incentives for datacentres to site there, which is why they have so many. Meanwhile, the electricity price today is just slightly higher than it was in 2000, corrected for inflation, and lower than it was in 2010.

Also, turning off the lights in empty rooms is something we learned to do as soon as we were tall enough to reach a light switch. The fact that adults have to be told to do this suggests electricity is still too cheap in Henrico County.

This isn't a new thing. Soviet doctrine for dealing with carriers was to fire as many missiles as they could at them to overwhelm their defences.

The US focus on expensive, highly capable weapons isn't baseless. The US military is designed to project power, and projecting power is expensive. If you're going to ship equipment halfway around the world and support it there, it might as well be the best you can make. That is very different from Ukraine or South Korea where they are, or expect to, fight in their literal back yards.

Expensive invading armies have always been vulnerable to the defending swarm, from hoplites and knights to empires getting their asses kicked in Afghanistan, Vietnam or Iran.

The people building the datacentres had a plan. The people approving them, and offering big tax incentives, also had a plan. Part of that plan was electricity rates going up.
