That's all a far stretch from the idea of interacting with someone who you know has a camera pointed at you all time.
Glass is new form of something that is currently: done covertly (hidden cams, sneaky smartphone use), obtrusively and temporarily (holding up a camera/smartphone) or by entities that already eschew social convention for their own business ends (security).
I see the act of wearing glass as a social confrontation. A dare that says the wearer think upping the intrusiveness and pervasiveness of recording should be fine because Google said so. And the reaction to the first roll out shows that people feel similarly.
This sort of notion ignores major realities of Google Glass: That it is not realistically capable of continuous recording, and that taking a photo with it has always been pretty obvious/distinct of a behavior.
If I wanted to take a photo of you with Glass, you'd have plenty of time to turn away, put your hand up, or whatever. And you'd certainly know I was doing it.
Not bothering with privacy rules because of on the technical constraints of today's technology is a dangerous game, because when better technology comes along you might find what "everyone does" is already on the wrong side of all the clear lines in the sand.
I mean, 50 years ago it would have been ridiculous to suggest the government could transcribe and search all phone calls - consider the incredible cost of all those typists, filing cabinets and reel-to-reel tapes! If someone had said "because we already have technical constraints, there's no need for ethical or legal constraints" we'd be in a difficult position when the technically impossible became possible.
Sure, but this is no different than smartphones. The parent comment above mine says Glass is a "new form", but it really isn't. It's just an Android device with a worse-than-average camera and a worse-than-average battery life and a worse-than-average capability to covertly record other people.
In the vein that you can buy a pen camera that'll do a much better job for $30, worrying specifically about Glass seems silly.
