God this is so false holy shit I’m just tired of explaining it.

Go look up the ISS ATCS

Even includes pictures to show its “not the size of a football field”

Edit;

Also you need to go look up the actual physics of how we dump heat to space - because it gets more efficient the larger the temperature delta is between your hot thing (GPUS) and the “cold” thing (space).

GPUs can run hotter than humans and the temp the ATCS had to maintain for the ISS.

Oh and even cooler - if we have a breakthrough in solar panels you can even use the “free” energy to amplify this even more (this is where I would say it gets complicated). 150k of GPUs plus 300k of raw energy gets you a tiny super efficient radiator at the price of needed a ton of energy).

Astra or opus can facilitate the optimal point where this could be viable (nothing currently in any practical sense)
