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.)
