Though currently too expensive for mass production, new computing technology is replacing electrons and copper wiring with photons that can carry information at light speed. “Ever since the first optical transistors were developed in the late 1980s, researchers have dreamed of building a light-powered computer, radiating with knowledge. Yet this breakthrough has proved elusive. Now, however, new developments mean that optical technologies are starting to appear inside computers.”
