For real. Thermal regulation of spacecraft is a problem that current, non-data center, satellites are struggling with and increasing the load by orders of magnitude isn’t going to make things easier. You can easily calculate the area needed for radiative heat transfer for a perfect radiator and you quickly end up with some gargantuan panels. Perfect radiators are also perfect absorbers, so the whole system goes to shit if the panel isn’t facing deep space.
