Great comment on hardware and maintenance costs, and in comparison Elon wrote "My estimate is that within 2 to 3 years, the lowest cost way to generate AI compute will be in space." It's a pity this reads like the entire acquisition of xAi is based on "Elon's napkin math" (maybe he checked it with Grok)

The deal they made values xAI at $230 Billion. It’s a made up number, with no trustworthy financial justification to back it up. It is set to provide a certain return to xAI’s investors (the valuation decides the amount you get per share), who in turn are bailing out the earlier acquisition of X (Twitter). All of this is basically a shell game where Elon is using one company to bail out another. It’s a way of reducing the risk of new ventures by spreading them out between his companies. It’s also really bad for SpaceX employees and investors, who are basically subsidizing other companies.

The thing is, everyone knows Elon is not a real CEO of any of these companies. There isn’t enough time to even be the CEO of one company and a parent. This guy has 10 companies and 10 children. He’s just holding the position and preventing others from being in that position, so he can enact changes like this. And his boards are all stacked with family members, close friends, and sycophants who won’t oppose his agenda.

Can you provide a link for that quote, because that quote is absolute stupidity.

He's bailing out one of his failing ventures with one of his so far successful ones. The BS napkin math isn't the reason he's doing it. It's the excuse for doing it.
