This scares me. I mean, notifications are already known to cause a great amount of problems, it is changing our brains, making our attentions spans shorter and more frail, I already hate even the fact I am carrying a mobile phone, it disrupts me, take away my attention from what I should be doing... SMS to me is even worse, it is very intrusive, distracting, and now that I got used in talking to girlfriends with SMS I noticed that I am getting "addicted" to devices, instead of people.
To me, Google Glass, and similar technology, is awesome, neat, interesting, but dangerous, very dangerous, it might have very serious consequences on how we work as biological beings.
