Gary - I started this parallel processing business and it appears that
it was not the best choice for making my point, which really did not
have to do with computation speed as much as with executing many
processes in parallel. My only point was that when there is a huge
community of similar organisms, each with evolutionary possibilities,
that a huge numbers of different possible paths will be explored
...essentially in parallel. If you have an objective, but that objective
is the outcome of some probabilistic process and the actual probability
for the occurrence is low, then you might reasonably do what it takes to
improve the probability of the desired outcome. That's why neutrino
detection tanks and photomultiplier arrays are huge. In the current
context, it occurred to me some time ago that this may also be the
reason for the universe being so immense.
