How far are we from just using photon to run our computer instead of primarily relying to electron/electricity?

Is there anything that prevent a turing complete system that uses light/optic/photon to run instead of primarily using electron/electricity?

Not even close.

Photonics chips and programable photonics are not a way to substitute conventional electronics, but a replacement/complement for some areas of the field where electronics is not efficient.
