AR/VR is likely to be the logical progression of physical screens, it's just we're not there yet. And it's not even that the current tech is that bad, it's just too clunky and cumbersome given the limited quality of the experiences at the moment.
I think as the tech becomes less cumbersome and the experiences get better you'll start to see apps that people actually find interesting / useful.
The whole cartoon virtual office stuff Zuck was pushing a couple of years back made it look like a joke. Given where the technology is enterprise productivity apps are clearly not the right product. If they instead invested in interesting AR/VR games and experiences I think they would have had more success. Imo the best stuff on the Oculus is the 3D video experiences and first person video games. But for some reason this isn't where Meta is investing to sell the tech.
