Meanwhile, on Vive, you could stand up, walk around, and manipulate the world with two tracked remotes.

Issue is that if I remember correctly the vive was an outside-in concept that required base stations to be setup. So you lose the cable, but are still bound by location. And importantly also needs a pc aswell. So still far away from standalone.

I think the core issue is that every piece of new technology so far has helped us get lazier. People used to walk around an office, then they sat at a computer, now they carry their computer with them and do things from the couch.

Nobody wants to get up to do things if they can avoid it, and that’s the only real benefit VR/AR provides

But I think VR/AR could make us lazier:

For VR the promise is immersion. You get to experience a concert, sport event, unique experience or exotic place from your own living room. And for many of that it is just fine to sit on a couch and still have a benefit from the technology.

For AR i think it's a bit more productivity focused. For example less need to train personel, if you can project every instruction into their field of view.
