How much smaller can it get?
I mean when it comes to technology be it military or commercial, communications or transportaitons, science or entertainment - How much smaller and how much more compact can our designs be rendered. Everything is becoming hand held and even smaller. I see people of various wealth walking down the streets with little glowing blue things in their ear talking to themselves and I think: Either they're crazy or I'm crazy.
SciFi keeps talking about digital data that can be stored on a single clear strip of imprinted material no bigger than a thumb and nano machines constructed out of protein that can be programed to build even smaller nano machines.
Is there a threshold as to how small in scale our technology can be reduced? How much longer will it be before separate technological functions are seemed together in uniform making individual devices obsolete?
