Do you mean to suggest that computer hardware does not need to be cooled when it is in space? Or that it is trivial and easier to do this in space compared to on Earth? I don’t understand either claim, if so.

The computer hardware only needs to run enough AI compute to be smart enough to convince Musk that it's working. It should be fine.
Superconductors. Average temperature in space is around 4 K.
Even assuming that this la-la-land idea has merit, the equilibrium temperature at the Earth's orbit is 250 Kelvin (around -20C). The space around the Earth is _hot_.
There are people literally working on accomplishing this. I don’t understand what’s with the arrogance and skepticism.
Edit: Not trying to single out the above commenter, just the general “air” around this in all the comments.
I honestly believed folks on HN are generally more open minded. There’s a trillion dollar merger happening the sole basis of which is the topic of this article. One of those companies put 6-8,000 satellites to space on its own dime.
It’s not a stretch, had they put 5 GPUs in each of those satellites, they would have had a 40,000 GPU datacenter in space.

you do know about the Sun? Earth? and the Moon? where would you get this 4 kelvin?
