AR has a huge battery life and size problem. The amount of video processing that thing would need to do to be useful, would result in an enormous device with an hour or two of battery life. Rendering it useless for any real world consumer application.

On top of that it has a gigantic privacy and surveillance problem.

And if that wouldn't be enough, what the heck are you going to do with it? Everything an AR headset could do, you can do today with your phone already. There is very little need to wear that functionality on your head all the time.

VR is just a marketing hype to collect VC money, that's it.

You know all those programmer memes about screen arrangement? You could have them all and more with a single headset.
