I've seen like, max 4 people wearing them in public in the bay, and that was like, 10 months ago. I forgot that they were even a thing, but apparently so did their target demo.
I'm in LA. Westside. Work in the entertainment industry. Surrounded by B-listers all day long. I've never actually seen a pair. Had a friend who qualified as an explorer. He asked me if he should buy them. I asked "what are they going for on eBay?" He responded with "didn't think of that... holy shit. Entering credit card info now." Apparently he flipped 'em for a good $700 profit without so much as opening the box. Closest I've gotten to Google Glass - advising a friend to investigate profiteering instead of turning them down cold.
There are a few in Boulder. People own a couple, and a pair that someone donated to the library that I got to try. It was cool for like five minutes, but everything new is cool for five minutes. Then I felt like a massive douche. I see see them on the street, and think the people wearing them are massive douches. I can't help it.
Literally the only thing I could come up with for using them is make protocols for Jove doing lab stuff. That hardly necessitates some goofy future goggles. I've reached a personal point of tech saturation, someone is gonna have to seriously come up with something out-of-the-box for me to buy anything farther down the rabbit hole than the (purely masturbatory) LG G3 I just got. Fitbit? Amazon Echo? All this consumer tech shit flies in the bay (on a 30 foot tall wave of hype) cause you have young, tech-hungry folks with no kids, okay with being early adopters, with plenty of disposable income and a religious outlook on optimizing and quantifying every second of their lives. And most of it is just outsourced apps. The incentive just isn't there. 3-D printing? I have your Neotechnological Luddism thread stickied forever cause it's so on point. Ran it by the mechanical engineer I work with and he laughed and said "pretty much" and that whatever you could ever do with that would never be to spec enough to function properly unless the thing you made was designed to be constantly fixed , tossed out readily and re-made, or non-vital. He did mention one application that had arisen because of some of the concepts underlying it in the manufacturing process, but then again, that was just the slow creep of progress on already well-vetted processes. nothing really "disruptive". just traditional engineering.
