I am just honestly confused. There seem to be no logical reason for it, except that it would raise the stock value of rocket producers like SpaceX and Blue Origin.
I remember watching a real engineering video, the white paper for it doesn't go into properly explaining the cooling mechanism. There were plenty of other problems too, but this alone was enough for me to know it's running on pure hopium.
Oh and you cannot just use the corporate maths in this and not count initial costs, and costs of assembling the whole thing. Estimated area of solar panels for a datacenter of 5GW was 12.5km² assuming the best of the solar technologies used. The initial cost of putting it up there would be so high, it might even dwarf the lifetime operation cost.
In my opinion, it's just another grift like hyperloop ko keep the AI bubble from popping.
Edit:5 not 4gw
Edit 2: I had watched the video long ago, and I glossed over a lot of things,
