I want this meeting to have higher immersion representations of the rest of the people in the meeting than boxes on a screen. I want to be able to shift my view to focus more on individuals. I want to be able to have a meeting with 40 people where I could still focus on a single person and see them with high-fidelity, instead of just having 20 of the boxes at low-res in front of me, with the rest off-screen. I want less eyestrain because I'm not just staring at a flat wall but my eyes are moving and shifting and re-focusing more. I want to have depth to things. I want the ability to have a quiet side convo off to the side. I want the ability to write on a whiteboard off to the side that people can look at when they want instead of taking-over the entire viewport for everybody. All things I could do in the real world, but would be very hard to make seamless without a real-world interaction model.

Again, we clearly aren't there yet. But it's easy to imagine something better than what we have today.
