Um, okay. Specifically, glasses don't try to do any kind of gaze tracking, gesture recognition, spacial awareness, any kind of 3d, depth, or immersion.

You could add more cameras and lidar for depth, yes, but then you'd also need a display for the other eye, and you still wouldn't be able to do immersion because your displays are transparent and have a tiny FOV, and you're also not doing passthrough, so why do you need the cameras again? And so on.

The XReal and Magic leap glasses have some of those things. Hololens had it before that. There's not a dream device yet but its clearly the north star for those and the Meta devices.
