It adds presence, which is the main reason business types currently don't like video conferencing and still choose to travel when they really don't need to. People want to be around other people, in their actual presence, they don't get that from video conferencing. Lack of presence is why telecommuting hasn't really taken over and why companies still bother with the overhead of a real office. People are social animals, they want to be around other people, not around screens with other people's faces on them. Presence is far more than just turning your head.

Yes, that's called presence, and that's what VR brings that video conferencing doesn't.
