They all keep announcing AR features for their devices and operating systems, even though those are very niche except as a "gee isn't that nifty" demo on current hardware—anyone who's held a phone or tablet or Gameboy or whatever up to interact with these things can attest it's pretty terrible overall UX, even if it's really cool as a demo. Glasses fix that problem. I assume the reason companies are continuing development of those capabilities is that they're pretty sure AR glasses aren't too far off. Seems like a much more tractable problem than self-driving, anyway—mostly a waiting game for battery and display/input tech to hit just the right spot and for someone to package it just right, like smartphones were.
