I personally question the goal of fighting it. More and more I begin to believe that it's "privacy vs. progress of mankind - choose one". Privacy for privacy's sake is not something I think is important - the problem is always with the ways lack of it could be abused. I can't see how we can save privacy without getting rid of computers - after all, even if you reduce number of sensors, the remaining void can be filled back by throwing more computing power at data you can get.
