I didn't know that corporate proselytizing was part of your job description. Do they score you on this in performance reviews? :-P Joking aside, this video . . . what does the author intend to prove? As stated here several times already, he'd have gotten those reactions with or without a camera. As far as Glass goes, I can see some serious privacy concerns here, especially when we pair this massive data mine (millions of pics being taken all over the place) with facial recognition software, date/time stamps, and geotagging of photos -- over time, Google will have collected a potential database of millions of people's whereabouts at various times and, if Glass becomes ubiquitous enough, will eventually be able to reconstruct the movement patterns of people who don't even use Google products. That's a bit worrying. And keep in mind it's not just Google that you need worry about. We already have problems with law enforcement requesting information from service providers without a warrant; imagine when the information available to them is no longer limited to just call records, but your entire locational history.
