Phones continue to be a bigger or equivalent privacy threat to the individual user and others than Glass ever was. The ability to discreetly take photos and short, low-quality videos also continues to be something highly possible with phones and other consumer tech.

One can at least assume that most people carrying phones don't have their microphone and camera on all the time - with Glass, that intrusion into privacy is designed to be unavoidable.

There is again absolutely no difference between phones and glass in this regard... Android phones now have trigger word detection ("OK Google") available as well, which is all that glass did. Again like a phone, the camera is only on when triggered.

The only real difference is positioning, but you can hold a phone up, and most people won't notice.

Why don't you go spend a day with your cellphone taped to your forehead recording video and see how many people notice?
