I think it's easy to dismiss Google Glass because it's never been "necessary", in the entire history of human civilization, to have a computer on your face. But in order to test the "is this a fad or is this truly transformative" question, my guess is that at its core there is no question this is a transformative technology. Here's how I've reasoned to this conclusion. Having an unobtrusive computer on your face, where you get no-friction, continuous access to the user's basic senses of sight and sound while they're out living their lives (far more time than your typical person spends sitting in front of a computer), is what this is all about. If you can't imagine uses for computers unless we're sitting in front of them or holding them in our laps, my hunch is you're not very bullish on human innovation.
