For a bandwidth-slow system, you split off a lot of independent packages
and rendezvous with them a second, minute, or hour later. You don't get
to increase the size of your largest high-speed thought, but you can have
large but very slow thoughts, or a huge number of small and fast
thoughts. Distributing a human brain over the Internet would slow it
down. A seed AI distributing verself over the Internet would need to
change the character of vis cognition, but after that could take full
advantage of computing power.
I'm sure you can do a mathematical proof that the Internet is
dumbfoundingly slow if you want to maintain S=1, as in the human brain,
where the characteristic communication delay time from an element to any
other element is on the order of the a single tick of a computing
element's clock speed. But all that analysis proves is that cognition
distributed over the Internet has very high S and that local packets of
mind are isolated for millions, billions, or even trillions of ticks.
However, you can say nothing at all about how much of an inefficiency this
represents at the *cognitive* level.
