This is actually a downside of the Vision Pro.
If I haven't seen someone in a while and vice versa, isn't one of the points of a Zoom call to see what that person looks like at the moment and not what the person looked like months ago, a year ago, or whenever the "Persona" was created? Or are people going to update their "Persona" every time their appearance changes (i.e. you grow or shave off a beard; you grow out your hair or cut off your long hair; etc.)? You can't even show off a new tattoo.
Think back to how people were using Zoom to keep in touch with friends and family members during the pandemic. I guess people will have to fall back to using FaceTime on their iPhone/iPad/Mac.
