Well, just to think, one day, they will invent a big room that is actually filled with A.I on the outside of a certain wall of some sort lets just say. You start it up, and then a hollographic yet touchable menu pops up, you can pretty much go on from there, if you've seen Futurama, some scientists are already taking that idea into consideration. I mean, look at the new brain helmet they invented this year, its not even out yet, but you attatch it to your head, and it reads your brain waves and transmits them into the game copying every command that you throw to it.
We are growing even closer to technology as we speak.
