> There's nothing that can be done VR that can't be done outside of VR. That is much like saying there's nothing that can be done in a telephone call that can't be done by telegraph. You just pass around information. I believe the killer application of VR will be tele-presense. Avoid the traffic jams and airport delays. You could say we can already have a video conference. But the point is that video-conference is simply not Hi-Fi enough. It is not the same thing as having the people in the same building and room actually. That is why people still do business-travel at great cost even though they can have a video-chat or video-conference. It's another question as to when VR will become Hi-Fi enough to enable tele-presence almost indistuinguishable from real presense. 5G may not be enough. We may need 6G. But once we're there there's much less need for business-travel, commuting will be done for pleasure not for business.
