If you're going to speculate on what's next for communication, it's probably best to follow the technology.
When everyone switched to more remote interactions during the pandemic, it was natural to just really ramp up the technology they were already using and a lot of people were upgrading their video and audio gear to make videos anyway.
Not clear to me what is next. I'm pretty sure most people don't want a more immersive experience most of the time and some percentage of people resent peer pressure to be on video as it is--as noted in various comments.
ADDED: I do agree with one of the points I think Ben is making. There is still a lot of UX work that could go into simplifying screen sharing and other, for lack of a better term, multi-mode interactions.
