Signals in the brain hop from neuron to neuron at a speed of roughly 390 feet per second. Light, on the other hand, travels 186,282 miles in a second. Imagine the possibilities if we were that quick-witted.

Well, computers are getting there.

Researchers from UCLA on Thursday revealed a 3D-printed, optical neural network that allows computers to solve complex mathematical computations at the speed of light.

In other words, we donâ€™t stand a chance.

Hyperbole aside, researchers bel
