For decades now there have been privacybusting technologies to which I have no easy and convenient countermeasures (long-range cameras, tiny audio recorders and radio transmitters, etc.), but I don't feel threatened by them. I feel (rightly or wrongly) that my privacy is adequately protected by a combination of other people's sheer lack of interest in my life -- I'm a fairly ordinary person -- and by social constraints. When such respect is widespread, snooping into other people's lives is disapproved of. I think this will go on providing protection which, while not perfect, is enough for most ordinary people to feel comfortable, and that new snooping technologies will not fundamentally change the picture.
As long as we live and breathe we'll be paranoid. We always have to be careful, but it isn't going to stop the movement of this technology.
