I do think these kinds of "virtual presence" apps are possible and exciting - and also I think there are huge new challenges that come with the Vision Pro's better spatial computing. If you are in a video game (like fortnight) you easily forgive a lot of jank - your brain isn't expecting it. On the flip side, people will not like someone jumping around "in space" right next to them. Same goes for reproducing movements in avatars.

You can always choose a lower fidelity co-presence, but again if you are doing that why are you wearing the heavy goggles? Just get a discord server and watch on there. I think there are very real technical challenges to combining all of the important aspects, but it is also the category of experience I am most excited by.
