Nope, because we already could have had that with VR/AR glasses, and while there are some (even impressive) options now, they aren't mainstream. Neither are the 'apps', nor the content interoperable, exchangable.
Furthermore I see nothing wrong with the desktop metaphor, it's just that we mostly only had a miserable magnifying glass, giving only a small viewport into a crammed childs toy, instead of real large high-resolution screens as can be had now, or sensible virtual desktops for more common sizes. To be expanded by "Metisse", an early 2.5D extension for FVWM, and later "User Interface Faćades". Maybe with some Zoomable UI sprinkled on top, like in https://eaglemode.sourceforge.net/ or whatever the clandestine weirdos from https://arcan-fe.com/ may come up with. (IF. EVER.)
AR/VR development in this space is a massive timesink for all the wrong reasons.
Hardware vendors absolutely suck here. Everyone is openly or quietly dreaming of the vertically integrated 'app-store tax' being their real source of revenue rather than selling devices.
This means that if you don't want to fuzz around with half-baked proprietary SDKs that break more often than they do what they're supposed to, you get to sit around reverse engineering. As fun as that can be, it's much less so when that is not what you set out to be doing. Half my electronics 'donation boards bin' is discarded HMDs and input devices by now.
Even in the quirky missed opportunities like Tilt5 you have this situation.
There are other 'glasses' systems in industrial use, giving engineers/technicians plans overlaid into their augmented reality. Usually voice activated. So that exists. Less cumbersome than that Apple or Metaverse stuff. Because industrial users won't have any of that. (mostly)
