Yes, I’ve worked on spacecraft and you have to put about as much effort into dissipating your energy as collecting it. The benefits I’ve heard claimed for space based compute are minor at best, and the economic downsides of cooling are show-stopping before even considering the (many) other negatives. Electronics also have to run much hotter than otherwise if your only cooling method is radiation. I’m honestly struggling to understand why some people that I normally consider reasonable and realistic are giving it much consideration.
