I never questioned it.

Space is also extremely cold, and if it's as dense as Musk cooling won't be an issue.

I can't tell how many layers of sarcasm are here, but I just want to highlight that aktshually cooling in space is quite difficult because there is no convection, so the only cooling option is radiative. Which gets a bit hard when the satellite gets blasted by the sun.

The ISS doesn't have problems staying warm, it has problems cooling off.

It does say he's planning an AI sun, I'm guessing that's the temperature you need to run at for radiation to work.

There are already large communication satellites that consume several kW of power.

Oh, good. So we only need to multiply that by 200 million times, per space datacenter.

The data center would still consist of many individual satellites, much like a earth based data center consists of many individual servers

tbh you could just combine them with starlink sats. didn't they just apply for (and get?) a license for 1 million sats? Stick a single racks worth of gpu power on those and hey presto you've just got yourself the largest ai cluster in the world by far.
