I don't get how everybody thinks that the picture / video taping part is the same as with smart phones.
With smart phones, I can actually tell when somebody's taking a photo of me, or recording a video. They need to pull the smart phone out and point it in my direction. I know what's going on.
With Google Glass, there's no way to know if the person who's wearing it is actually filming me right now. Which means that every time somebody wearing Google Glass is around, youre potentially getting videotaped without knowing it. To me, that's a BIG difference and would most certainly change the way I'd behave around people wearing Google Glass.
Which is why I think Google Glass sucks, big time.
It's basically the Web 2.0 / social media version of Orwell's 1983. If / when enough people use it, there's practically no unmonitored place left on earth. Thank you Google, great idea.
