Remember kiddos, it's not just about the privacy issues that we have here in America. Look at what the other countries are having to deal with now, their privacy is being completely violated in one way or another. The implementation of cameras, people tracking, and other types of identification systems are being misused; in no time they'll be dealing with zealous institutions who are willing to undermine the average citizen to "make" the world a better place.
"Today's robots are very primitive, capable of understanding only a few simple instructions such as 'go left', 'go right', and 'build car'." --John Sladek
