my reaction when people look at me while wearing google glass is, "please get that camera out of my face." i find it unnerving and sorta creepy to have a camera pointed at my face, and to me, while the glass is not just that, it is still a camera.
The idea that the person across the table have a recording device, and every second of our conversation can be scrutinized later or posted on some social network is very unnerving and mood-killing. I don't dinner with people with smartphone turned on to capture every spoken word for exactly same reason.
This resistance comes 'mostly' from the older generation, look at generation X, your kids. They give information freely, its a natural part of life their life, daily!
When I can walk out of my door and thousands people are feeding information 2 miles away about traffic on route to my work, or predictions of flu outbreaks are spotted before then happen saving hundreds of lives. This is a world where closed minded people don't guard information like there are special. A would where people give information to help others! The world is currently like China, closed minded and guarded. Role on generation X!
