I'm eagerly awaiting social VR. Since playing multiplayer games allows people of now to have unparalleled social interaction and insight into other person, being able to freely explore virtual worlds together would greatly increase integrity in society, even if at very least teaching various social skills.
Yeah, there's no reason humans can't interact with the physical world through auxiliary VR worlds. We already do this with websites, VR will eventually be an interface to interact as a connected robotic device.
At the same time, the person in VR would be giving learnable information to the robot while they are controlling it (e.g. like a driver for a self-driving car). Eventually, you could wade the robot off of VR and it would be able to carry out the task. So, VR could also be a way to teach robots.
