Cross section of Canon EF 600mm f/4L IS II USM lens
gollark: Oh, and there's the obvious probably-leading-to-terrible-consequences thing of being able to conveniently see the social media profiles of anyone you meet.
gollark: Some uses: if you are going shopping in a real-world shop you could get reviews displayed on the items you look at; it could be a more convenient interface for navigation apps; you could have an instructional video open while learning to do something (which is already doable on a phone, yes, but then you have to either hold or or stand it up somewhere, which is somewhat less convenient), and with some extra design work it could interactively highlight the things you're using; you could implement a real-world adblocker if there's some way to dim/opacify/draw attention away from certain bits of the display.
gollark: There's nothing you can't *technically* do with a phone, but a more convenient interface does a lot.
gollark: There are rather a lot of cool uses for being able to overlay information on reality.
gollark: I think you're being uncreative.
