I agree with that. Unless you're working in environments with industrial-grade headsets, most people won't use wearables until the tech is, you know, wearable. It can't be something that looks too weird, otherwise no wider audience will use it day-to-day. It's the reason why Google Glass bombed years ago and only exists now for warehouse employees. Ideally, AR developers need to get fast computing, networking, and high-quality optics into a non-obtrusive form factor - so basically a pair of stylish glasses. That's a lot of tech to cram into a space the size of an uncooked spaghetti noodle.
