Some people already are relatively capable of full immersion into fantasy, especially via video games, to the point of ignoring the outside world. I know plenty of people like this, it's a common personality makeup in some of my hobbies, and it can be debilitating.

I wonder how many people's jobs and social lives will actually eventually 100% take place inside of virtual reality spaces - or, for that matter, *game* spaces with the present tech we have now.
