A 500-MHz Alpha can add two 64-bit numbers in 2 ns, more or less.
My brain can't do so much as fire a neuron in 2,000,000 ns.
But my brain has a lot of neurons, because neurons are cheaper than
Alphas, and so it's actually capable of doing quite a bit.
I'd be happy if I could do so much as print out a 4-bit, 1-KHz-clock stack
machine on a piece of paper. The researchers I referred to at
POEM.princeton.edu seem to have much more than that in mind, although at a
little greater expense.
Does anyone know of cheap ways of printing semiconductor components onto
paper or transparency film? :)
