	This is especially true given the vastly different hardware
used in the two types of systems. A solutions that is effective for
the linear or nearly linear processing of an electronic computer might
well be *quite* different than a solution effective in the *massively*
parallel system that is found in even the simplest brain.
	Even the most massively parallel computer design now
contemplated is essentially just a glorified linear system compared to
a brain. The brain effectively has a nano-processor for each *bit* (or
perhaps each nibble). It is also extensively *pipelined*, having a
seperated physical stage for each stage of the computation. Thus the
eye itself(the retina) performs in parallel what amounts to 2d
derivative of the light flux! And that is *just* the eye. Try and get
a computer to do *that* for a complete multi-thousand pixel image in less
than a second! And then *continue* to do it, in real time, indefinately.
