Well here is a shot at answering the question.


Assumption is that a rational philosophical proof one way or the other
is not possible. One can create a finite state machine with either
electric or mechanical processes, today digital is more popular but we
could have nano-mechanical computers in the future.

BUT, we have seen two types of computing devices evolve, neurological
and computers, and both use electrical impulse, so it would seem that
has proven itself over billions of years as the best way to transmit
state information.

Hi:

AFAIK, nanobots will use molecular conformation changes (e.g.,
Drexler's "mechanical" computation) or electronic energy-level
transitions to process internal information.

Drexler info:

Which has more advantages, mechanical computation or computation using
electronic energy-level transitions?


Thanks,
