Computers at the speed of light

Scientists said yesterday that they had achieved a long-sought goal of slowing waves of light to a relatively leisurely pace and using those harnessed pulses to store
an image.

Physicists said the new approach to taming light could hasten the arrival of a futuristic era in which computers and other devices will process information on optical beams instead of with electricity, which for all its spark is still cumbersome compared with light.

I'll I can say about this is WOW. Ok, and hope when computers are run by light instead of electrons, they have an operating system that is stable enough to run it.
