There is quite a bit of talk about Google Glass now that they have opened the demo for big idea people to apply for their own test units. There is more unknown than known at this stage, but I think the idea holds plenty of potential for the right scenarios. I’m not convinced that we’re going to see millions of people walking around with these things though. Perhaps one day we’ll be completely comfortable with the prospect of a camera and microphone capturing our every move without our knowledge, but we still cling to a notion of privacy that should allow us to disengage when we feel compelled. I wonder if we’ll see ‘privacy’ devices that scramble nearby signals. Hmm.
