How far in development are CPU's that only use light as their input and have a
series of optical logic gates to do processing? Alternatively they have
electric inputs to power laser emitting diodes. Does something exist yet in
the 21st century? I'd imagine it would have incredible power
I don't think it's a real OpenBSD question, but let me try to answer.
As far as I know there are no real (useful) optical processors yet.
A while ago there was an new company who promised the EnLight 256.
An optical processor for highly specialized tasks, but i never heard
about
