Just read about light based hardware over at TechSpot. What do you think about it?

Here's the link. Can't help but think this is 10 years out for practical application.
Then why can't light escape a black hole? Why is gravitational lensing possible?Photons have no mass

Photons have no mass so I dont know how they plan to contain or maneuver them through the intricate framework of a CPU.

Gravity is caused by what amounts to a bend in spacetime. Light travels along a straight path, yes, but a black hole is a really extreme bend, sort of like a pit. Also, it's possible the light may eventually escape, but as hawking radiation.
I thought electric current already moved at nearly the speed of light, since it's not the actual speed of electron travel but the speed of wave propagation of current flow.
Sure, nothing is faster than light, but electricity isn't exactly slow. The best part I can think of moving to photons would be removing resistive losses (although you'd be trading I2R for some other type of loss - everything degrades to thermal in the end)
