> I did not check to see if the iPhone in his pocket was recording, nor did I really focus on his button up shirt to see if there was a tiny camera recording me.
You know why? Because the phone was in his pocket, and if a camera was on his shirt, it was very well-hidden.
The fact that Glass lives on someone's face, the thing our brains are hard-wired to focus on, punctures a hole in manufactured normalcy and brings the issue right to the surface. Especially given that the whole point is to use it: all it will take is someone drifting off in conversation while staring into their mini-screen, or blurting out "Oh, that's so funny, I just put it on YouTube", and it'll leave a sour taste with everybody else.
I can't predict whether or not Glass will succeed. I can confidently predict, however, that there will be a strong social backlash.
