Even if you simplify it a great deal, it is still impressive. Suppose you
write a program to scale, offset and sum each of the 100k inputs, and that
loop takes 10 instructions, and you are running on a 1000 MIPS machine, well,
that lets you do 1000 firings a second, which is about what the biology can
do. Think of how smart you could be if you could intentionally, and exactly,
wire up even a tiny fraction of your neurons. (Perhaps even smart enough to
wire up the rest.)
