Absolutely needed: to get high efficiency for this beast ... as it gets better, we'll become too dependent.

"all of this growth is for a new technology that’s still finding its footing, and in many applications—education, medical advice, legal analysis—might be the wrong tool for the job,,,"

Solar powered server farms in space. Self-powered, self-cooling, 'outside the environment'. Is this a stupid idea?

Edit: So it would seem the answer is yes. Good chat :) Thanks.

I don’t understand the self-cooling. Isn’t it harder to keep things cool in space since there is no conduction or convection cooling? I mean everything is in a vacuum. The only place for heat to go is radiative and that’s terribly inefficient. Seems like a massive engineering problem.

It is, infrared radiators weight a shit ton and are inefficient, big and unwieldy. Still the only viable option for cooling in space. AI would take an hugemongous square footage of it just so the GPUs won't melt.

I thought so.
