We already live in virtual reality—through tv, books, games, Internet, music, and dreaming.

There is a site online called Second Life, which is a virtual word kind of environment. I spent a fair amount of time in there, it can be quite addictive. I have found a fair number of people in there seem to have some issue in dealing with real life; Second Life gives them an opportunity to experience things from a different perspective. It's far from full immersion, but with new peripherals, it is getting closer. If it did become full immersion, I would try it out just to see what it was like.

Nope.

We live in a matrix, just put the puzzle together in plain sight.

Sounds like a holodeck. I’d get addicted to it for sure.
