Data centres will not be moving to space. The physics and economics don't work.
It's not that it can't be done at all, but heat dissipation at scale in space is an insane engineering challenge, the tech to make giant radiators work doesn't exist yet, and even if it did it would extremely costly to develop and deploy.
Musk is a textbook narcissist. His consistent pattern is to make grandiose promises - literal future faking - fulfil a small percentage of them, then make even bigger and more grandiose promises and hope investors have a short memory. (They do.)
As a narcissist his primary relationship orientation is contempt for others. He's more interested in damaging projects he doesn't like - like the left-leaning community on the original Twitter, using promises of Hyperloop to kill high speed rail, ignoring the CSA from Grok, and of course the USAid fiasco - than seeing through the projects he claims to be developing to completion.
He fits in perfectly with Thiel, Altman, and the rest. The tech is sometimes interesting, but the alignment is fundamentally hostile to the rest of humanity.

Different problem.
Cooling can be done in space, it's a normal problem; not easy, nothing in space is easy, but on the scale of space it is normal.
However, at the temperature you would run a chip at, a radiator you make for space will just work better, reject more heat, if you leave it on the ground.
We get convective cooling down here as well as radiative. At operational temperature, convection more than makes up for the atmosphere being a heat bath at ~20 C or whatever.

You are overstating the engineering difficulty. Starlink constellation already dissipates around 100MW.
