I mean you can easily create your own fully meshed P2P group video chat in your browser just using a little bit of JS that would support everyone running 4k, but it will fail the moment you get more than 3-8 people as each persons video stream is eating 25mbps for every side of a peer connection (or 2x per edge in the graph.) A huge part of group video chat is still "hacks" like downsampling non-speaking participants so the bandwidth doesn't kill the connection. As we get fatter pipes and faster GPUs streaming will become better. edit: I mean... I could see a future where realtime video feeds never get super high resolution and everything effectively becomes a relatively seemless AI recreation where only facial movement data is transmitted similar to how game engines work now.
