> Face recognition, voice recognition, biometrics, kinematics, writing style, and of course metadata will make public an astounding amount of information. A video of a random group of strangers will be trivial to index and identify every individual through the above techniques. A shockingly detailed account of everyone's lives, where they've been, who they've met, what they've purchased, and so on will be determinable using, eventually, relatively little cost in computing power. Indeed. I can't imagine it will be many years before we see a similar video, except now with a Terminator-style overlay (that the wearer also sees in real time) indicating the name, age, occupation, marital status, etc. of every person. I've never been afraid of technology before, but this really doesn't seem to me like a future society I'd like to live in. "Oh look, that girl over there just got dumped according to Facebook." "Haha, that guy that dresses like a bigshot really flips burger for a living!" "That family over there is from France." ... and so forth. Others in this thread have said that it's just a gradual line of change from everybody carrying cellphones with cameras and an Internet connection. I sort of disagree. Even after smartphones became ubiquitous, it's not socially acceptable to obviously point it at strangers. Pointing your glasses in their general direction is, though. I wonder if I'm just going through the same line of thought my parents did when they realized the Internet was here to stay in every part of life. On the other hand, there's always masks :-)
