Interesting, to say the least. The potential data stream from that sort of deeply person(al) bugging/tracking is incredible--always has been. As well as scary.
When I tended bar at a place near the University while I took post-grad courses in sociology and social psychology, I used to fantasize about bugging every bar table in the joint, and analyzing the web of relationships, the ebb and flow of ideas, the positional maneuvering, the unedited emergence of a deeper set of political and social beliefs- the comments when a black duo was on stage (me and Smitty)-- but I never had any doubt as to the Orwellian the way that data would inevitably be used. Some boxes hold great treasure--but nasty little snakes, too. "There is mysterious music in democracy, when people decide to believe in themselves." ---Bill Greider, The Nation.
It is like Psyche lighting the oil lamp--before you do it, stop and think! Not only is it, "What do you want to know?" but more importantly, "What will happen when you (try to) find out?"
The bill is itemized: 1) What is the price (consequences) of asking? 2) What happens to you when you have the answer a) because of how it changes you and, b) how it changes others when they know you know?
In your example you are thinking of a whole technology, and of course the problem is summarized: How can (will) it be (ab)used?
To the case at hand: Not only do cell phones cause brain cancer, but they enable the government--or anybody with money and access--to trace your movements and model your behavior, collectively or individually, to the advantage of . . . who? What's not to like!
