VRChat seems to have landed on something close to the right balance of whatever it takes to make it happen. It's apparently easy enough for someone to make a whole meme world for an event in the news in time for it to be relevant: https://www.theverge.com/tldr/2020/11/9/21557029/four-season...
If only. Arguably, part of their secret sauce is their restrictiveness of new users. You have to spend quite a bit of time in-game to gain the ability to even be seen by a lot of other users, and more still to be able to upload avatars and worlds. I'd planned on opening an art gallery space on the platform this summer, only to find that I didn't have enough friends to reach the "trust" level necessary to upload worlds. It's probably a good thing for the quality of the community itself, but anathema to growth or casual use.
(And as for me, I'm stuck trying to figure out how to hack up a WebXR experience with, ah, limited programming skills. Until then, it should be at https://vrchat.com/home/launch?worldId=wrld_559152a2-44d3-44... , but it's inaccessible without adding me as a friend and accepting an invitation to an instance I spin up. So, practically useless. And support is no help in terms of what, exactly, I'd need to do to raise my trust level.)

VRChat or someone building on their proof of concept is likely to make it happen. It won't be Facebook with its VR Slack.
