I was watching a panel discussion on ubiquitous computing - the chip in the toaster, etc., and the vast, interconnected networks that are resulting from that. I have also been watching all the breakthroughs in optical tech, self-driving cars, and autonomous robots. Current civilian drones are now capable of tracking every human being and vehicle, inside a five square mile box, even within a city. No doubt the military can exceed that coverage.
What I've never understood is why people who are so unimportant that they couldn't possibly be of interest to anyone, much less a government, are so paranoid about people "snooping on them." Sure sounds like an overdose of self-importance to me. :-)
