It's much easier to find a country or jurisdiction that doesn't care about a bunch of data centers vs launching them into space. I don't get why we aren't building mixed use buildings, maybe the first floor can be retail and restaurants, the next two floors can be data centers, and then above that apartments.

Probably for the same reasons they aren't doing mixed use prison and restaurant buildings.

What you don't want to live near the newest poisonous abomination that the whiz kids dreamt up? Do you want China to take over America or something?

We also shouldn't overlook the fact that the proposal entirely glosses over the implication of the alternative benefits we might realize if humanity achieved the incredible engineering and technical capacity necessary to make this version of space AI happen.

Yeah it does not make a whole lot of sense as the useful lifespan of the gpus in 4-6 years. Sooo what happens when you need to upgrade or repair?

With zero energy cost it will run until it stops working or runs out of fuel, which I'm guessing is between 5-7 years.

But everyone is crazy about GPU’s right now. Why not ride that wave for extra investment? All the benefits transfer to all the other things we can do with it.

Only people who never interacted with data center reliability think it's doable to maintain servers with no human intervention.

This guy invented reusable rockets that land themselves. I'm sure xAI is not just one guy. Plenty of talented people work there.

I couldn't believe that was an actual quote from the article. It is. These people are legit insane.

No it's just Musk's Big Idea for spacex to hype it before IPO. It's their version of FSD, robots etc. You've got to hand it to him, he is a bullshitter par excellence.

How people still believe his bullshit is unfathomable.

In the past 40 years we’ve seen power per unit of compute decrease by over 40 million times. This says we need to put data centers in space because we can’t produce enough power on earth for AI. That won’t be the case as history has shown, but this is a great way to get AI money for your space ships if you’re going to IPO.

> We currently make around 1 TW of photovoltaic cells per year, globally. Doubling every three years; at that rate it would take about 30 years for 1TW to become 1000TW. Whether on not the trend continues largely depends on demand, but as of right now humanity seems to have an insatiable demand for power.

We’re not going to use 100% of our solar panel manufacturing capacity to power space data centers, specifically because everyone else on the ground is so power-hungry. If we’re being generous, it could maybe top out at 1%, which adds another ~20 years to your timeline for a total of 50. I think it’s safe to say this part is bunk (along with everything else about this plan which is also bunk).

We seem to be using 100% of our DRAM manufacturing for AI. So it's not completely out of the question.

Mixed-use buildings with restaurants on the lower floors and residential on the upper floors are very common. Not sure what prisons have to do with anything.

We don’t even have a habitable structure in space when the ISS falls, there is no world in which space datacenters are a thing in the next 10, I’d argue even 30 years. People really need to ground themselves in reality. Edit: okay Tiangong - but that is not a data center.

Ok then short SpaceX stock when it IPOs.

If you're hellbent on arguing with a cult, it will be much cheaper to go down to your local Church of Scientology and try to convince them that their e-meter doesn't work.

SpaceX is too big to fail. It's important for national security. I wonder if Elon wants to tangle all his businesses into SpaceX so they are all kept afloat by SpaceX's importance.

Why are we still supporting this person? His cars are being outclassed internationally and he's directly meddling in this countries politics. He spectacularly failed (or wasn't it blatantly misled) the CA government with regard to the tunneling, and damaged the public sector while shutting down oversight and regulatory bodies against his companies.

Where is the benefit? These awesome tech demos? It just screams charlatan to me on an epic scale. I see no reason a government shouldn't step in to assume control if its "too big to fail".
