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.
Hence the “dense as Musk” comment
> the only cooling option is radiative.
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.
