The big question is how to use maspar in an useful way. How do we run a
word processor or matlab in a maspar network?

This seems to be similar to the problems with process migration and
distributed computing, although in this case one can (probably) assume
identical processors at least.

I think it is mainly a programming problem - we are not very good at
creating parallel algorithms, and most obvious ways to do things for us
are serial when they should be parallel.

I think this would be ethical (if it could be done safely), since I
approve of all changes that increase the freedom of acting of a being
(after all, the child doesn't have to use it if it doesn't want it, and
is given new abilities). But I guess others disagree.

Sounds quite possible, the brain gobbles up a surprisingly large fraction
of our metabolism (was it 25%?). I think we would have to change the
development of the brain so that it grows further after birth (another
bottleneck [and a sick pun]). Perhaps development should be slowed
somewhat so that the brain can grow further, but I doubt parents could
stand a longer neonatal period! (Unless we engineer their hormones
too! :-)

This is what happens when the brain is injured. But I think the ass.
cortices contain a lot of independent connections that doesn't correspond
to any clear-cut regions.
