I'm convinced this is why Apple and Microsoft (among others) keep putting money into AR development. It clearly sucks to use right now, so it doesn't make a lot of sense that they're putting significant money into it... but when someone (possibly one of those two companies!) finally puts out AR glasses that aren't awful, they'll be ready.
I remain unsure whether Zuck is running that same playbook, or if he legitimately thought bulky-ass VR goggles were the way of the future and expects to have a smash-hit before marketable AR glasses exist.
