Low error rate, speed, power efficiency: pick two.

Biological systems (which have their large legacy baggage) do so dramatically
better than any current artificial systems that a generic comparison is laughable.

The fitness function of predator/prey in a limited resource environment
doesn't take kindly to brittle, nonrealtime systems with a very large power
envelope. There has been no evolutionary drive to evolve systems capable of
doing cryptography -- pattern recognition and molecular diversity has been
more than adequate for the task.

Computers don't get eaten nor do they starve -- yet.
