rather than giving me that "whatever" answer. For now, the trend is toward hybrid chips, and if all-Si can be used for all components, all-optical chips will follow in some not very distant future.
If you are happy with the speed microelectronics only chips can deliver, I'm not. I want to access a good Mullin Rouge show, or the Vienna philharmonic or whatever else on-line whenever I feel like. And I wish I live to do it (I'm growing a bit old, you know, so I don't have too much time to wait ...)
