This is why (the CPU left unchanged) it is possible to use neural
emulation over WAN, even 50 ms, 50 kByte/s WAN. Just make the
damn array large enough that processing it takes forever, so
that exchanging the interfaces won't be the bottleneck.

(Of course for practical reasons we wouldn't want to swap 
the array to rotating bits, since that incurs a six orders
of magntide random access penalty, at which point we could
as well become lumberjacks, or shepherds, so it would
take lots of crunch on each element of that array before
you can do that).
