How could this be so. Well, I should say multifunction pocket calculator, probably running something like Android in 5 to 10 years time.
I have been involved with a group that has a low powered chip with 144 processors that can do over 100 billion instructions per second that could be upgrade to do many many times more, suitable for a pocket camera maybe. But what I am really talking about is that they plan to release optical computers in the next 5 years, that will have more than a thousand times the processing power of present systems. Just a little advanced release optical processing circuit could make red code on a pocket scarlet 4.0 a push over. The sort of thing that a future advanced multifunction calculator might use. I aim to start work on a cheaper version of optical computing too.
