I wonder how many Google Glasses wearers will become Life Loggers? I meet them at conferences occasionally. Some people actively avoid them. There's something about standing face to face with someone taking a photo of you every X seconds that people find really unnerving. I certainly do. Real time video is worse and it's very different to CCTV.
How long before Google collects and mines all this video like they did with Google StreetView but in realtime? Combined with the huge advances in facial recognition the privacy implementations are frightening. It reminds me of the scifi film "The Entire History of You". [1]
In the future will people who want to opt out of face recognition and tracking have to wear identifiers*, e.g. QR codes, on their person when talking to Google Glasses users, much like Google's wifi policy? [2]
