Does it make me crazy that I've been fascinated by Professor Steve Mann for twenty years? I hope not. Then again, I don't want to look like him. Once it's properly inobtrusive then I'll look into then through it. For now I'm happy to work on my silly 7-segment LED hello-world repetitions on various MCUs and read on my large but not crazy large cell phone.
I've been moderately interested in him for ten... I keep waiting for him to come up with some cool reason to put up with all the hardware but you don't need Terminator vision unless you're the Terminator. You know, there's a metaphor there: If you're uncomfortable with your environment and don't wish to interact with it as an equal, all the HUDs and telemetry and shit give you power. But if you're actually interested in having a conversation with someone, all the interface tomfoolery is a barrier between you and them. I think Google Glass could be straight up invisible and it would still be a barrier to communication.
