The issue is that we have like 40 years of UX improvement for desktops and now have super high resolution monitors that make that UX experience usable. We have like 5 years for VR and 0 years with a high enough resolution to make it usable. I think once high resolution enough VR comes out it'll pretty much be "oh I don't need monitors anymore, but keyboards/mice are still pretty much ideal for text entry/knowledge work, so lets keep those. probably more standing desks also." The metaverse thing is a solution in search of a problem, and in Facebook's case, clearly a solution in search of more money.
