That is nice. But then why do fiber optic cables work? The data does need to be turned into photons, and back from photons into electrons at some point. So all of that has switching and has been done for a long time. Guess maybe lot of people like me are wondering why the technology for fiber optic cables can't be scaled down further to be used on chips.
