Here's what I've got: light based computation has been around since the 60's. Yet somehow it hasn't supplanted electricity-based chips. But now someone has made a chip for training AI out of it. I guess that would just be a GPU? Anyway it's more efficient because light. Furthermore, maybe someday this will be relevant to the quantum through some as-yet unimagined mechanism. But this is awesome because light is faster than electricity. It. Just. Is.
