Re the whole topic related to M brains, Jupiter brains and related,
nobody has ever answered my interrelated concerns of waste heat
dissipation and speed of light delays.  The laws of the universe, as I
understand them, don’t allow for physically large objects to be fast

I think the best we engineering inside these limits is large
computation systems spread over spheres and sunk in a cold ocean.  Of
course you can build large systems in space, but they would be
relatively large heat sinks with a limited node of computation.  Speed
of signals between nodes would be unbearably slow, with each isolated
by a huge communication delay.

That’s been my objection since Perry Metzgar started talking about
this topic back in the 1990s.
