While today's digital hardware is extremely impressive, it is clear
that the human retina's real time performance goes unchallenged.
Actually to simulate 10 milliseconds of the complete processing of
even a single nerve cell from the retina would require the solution
of about 500 simultaneous nonlinear differential equations 100 times
and would take at least several minutes of time on a Cray supercomputer.
Keeping in mind that there are 10 million or more such cells interacting
with each other in complex ways, it would take a minimum of 100 years of
Cray time to simulate what takes place in your eye many times each
second.
