Any good argument that anyone can think of for a scenario where smart eyewear will not be as ubiquitous as smart phones eventually? I understand the privacy argument, but that is not going to be enough. The ability to think or blink in a certain way and capture anything you see is too powerful a tool, alongside the augmented reality that is coming.
"Smart" glasses erode everyone's privacy unlike any other technology. Cameras and cell phones have to be held up to record. Glasses can stream effortlessly and continuously, without anyone's consent. If that is not reason enough to object what more do you want, my fist in your face?
I'm very deeply concerned about privacy, but a simple thing like an "on" or "recording" light on the glasses could alert people that recording is on.
