*I think Mr. Jupiter Brain will be composed of billions or trillions of
closely interlocked agents just as many modern AI's are, although they
usually only have a few hundred. Some of those agents would be generalists
and some of them would be specialists. Jupiter is about 85,000 miles in
diameter, light travels at 186,000 miles a second. So AT MOST it would take
about 0.46 seconds for one agent to send a message to another, and about
0.9 seconds for it to receive a reply. Except for very short messages that
demand a near instantaneous yes or no answer, and there wouldn't be many of
them, this delay would cause few problems and be compensated for by the
fact that the bandwidth between agents would be VASTLY wider than the one
the human brain uses to communicate between one side of the brain and the
other.  *


*Humans seem to have something similar to agents going on inside their
heads, but the extremely narrow bandwidth between agents means that a big
improvement in one often has little improvement in any other agent. That's
why somebody might be the best human chess player in the world but not be
particularly good at doing anything else. *
