Virtual Reality

I think eventually Virtual Reality will be huge. Bigger than TV, bigger than the Internet, bigger than smartphones, bigger than anything ever.

Eventually, after 200 years or so, virtual reality will be come indistinguishable from reality. You'll be able to experience anything you like. Any time in the past, anywhere in the world with bots interacting with you almost as realistically as real people. 

And one will be able to interact with real people in a shared virtual reality.

All this in perhaps as little as 200 years. Can't wait! Quite literally . .
