We may have admitted that the earth orbits the sun,  but it feels like we still believe the universe solely for us - maybe it does,  but asserting that as truth feels analogous to flat-earth assertions.

I have doubts about the whole idea of 'waste heat'.  Heat is
incredibly useful, especially in the depths of space.
You have to assume that the Jupiter Brain is only running computation
and has nothing else to do except get rid of heat. That seems really
unlikely to me.
There could be a whole civilisation living off that 'waste heat'!
(That's also the problem with the term 'global warming'. Most people
say they would quite like it to be warm).  :)
