It will soon be like air. Say you are walking down the street. Your sunglasses are also cameras. Each face you encounter is scanned and fed into an Internet pattern-search. Your glasses are also display screens.
Captions seem to accompany pedestrians and passing drivers, giving their names and compact bios.
You do an eye-flick, commanding a fresh view from an overhead satellite. As you stroll along, you know that others see you similarly captioned, indexed, biographed. Outlawing the tools will only ensure that common folk can't use them. That, in turn, will only serve the interests of the mighty. So we might as well have them too.
