He sold his failing but hype business to his soon-to-IPO successful but kinda boring business.
It's a way of laundering the debt and dumping into investors as he pitted different indexes against each other to force his way into one of them, and have people's 401k buy into them. Its a ton of money.
I wouldn't be surprised if Tesla is bought into spaceX in the future.
And you don't have to deal with any of the site selection stuff you have for terrestrial data centers. No NIMBYs. No politicians trying to extort bribes. No water problems.
In space there are no earthquakes, tornadoes, or floods.
I'm still skeptical. It's hard to believe it costs so much to build a data center on the ground that putting it into orbit is an economically viable alternative.
I'm not going to assert that large scale space compute will never happen, but I feel confident saying it won't happen this decade or next.
