There are actually many startups making software for online shared spaces for remote work with side conversations, etc. Or 3d shared working environments for VR or the desktop. There is also Discord which has text, video and voice chat which is really convenient (like two clicks). The Meta Quest Pro should be much better for AR/VR meetings. Also it's great for realistic table tennis and Demeo (kind of like D&D). It's fairly trivial to set up a way for a webrtc video call duo to split off from a group. I assume there is already a startup doing that. There are also co-working places in most cities now.
