I sort of like the idea of Google Glass but it makes me uneasy in the sense that it's a further and quite significant social encroachment, as if people staring at their phones all day wasn't already bad enough. So, in a sense Google Glass signifies to me that we've gone too far down a particular blind alley and we probably ought to do a reset and rethink what we want technology to do for us, and why.
There's also a sense that Google Glass is a product of the lunatics finally having taken over the asylum, in this case the lunatics being the one-time social outliers - nerds & geeks and what have you - only these days they're not so much outliers defined by poor social skills and bad hygiene as much as they're outliers with Lamborghinis who are increasingly architecting larger and larger parts of our tech dependent society.
And with Google Glass they're subconsciously having the last oppressive laugh by now insisting we all walk around wearing nerdy spectacles in their own image, like a post-modern nerd remake of Mao's communist China uniform.
My money's on the smart watch as a much more socially digestible form of personal tech.
