Am I the only one who thinks Google Glass is a bad idea? We already trusted our virtual life to google (emails, what we do, etc). Are we sure that we are ready to trust our real(physical) life too? Don't get me wrong... It seems like a cool project but I wouldn't use it, maybe I am getting too old :/
Privacy would have to built into the project on many layers. Without a push to do so from above, they won't.
