It's useless tech, that's why.

It's faster and more efficient to go to a website than fuss with a 3D environment, and when you're done you don't have to "leave", you can just close the tab. And you can have multiple tabs open at once and flick between them. VR is stupid slow and clumsy in comparison.

And AR us even dumber. I mean really, just what I want: MORE pop-up ads in my life, only now in real life!
