I think in general we all might be underestimating the social stigma that is going to come from being the guy walking around in public recording strangers. The examples in the article (e.g. drones) are tolerated because (a) people aren't aware its happening to them, and (b) that type of surveillance is usually limited to certain classes of atypical people / activities. Google Glass has problems with both (a) and (b) - people know you can be recording them, even if you aren't some kind of terrorist or police target. If all that stands between being able to record everything all the time is disabling a little red LED on the glasses, how soon before the typical person assumes ALL Google Glasses are recording ALL THE TIME?
