You Know, William Gibson totally called this.
And then there's:
This spreading, melting, flowing together of what once were distinct and separate media, that’s where I imagine we’re headed. Any linear narrative film, for instance, can serve as the armature for what we would think of as a virtual reality, but which Johnny X, eight-year-old end-point consumer, up the line, thinks of as how he looks at stuff. If he discovers, say, Steve McQueen in The Great Escape, he might idly pause to allow his avatar a freestyle Hong Kong kick-fest with the German guards in the prison camp. Just because he can. Because he’s always been able to. He doesn’t think about these things. He probably doesn’t fully understand that that hasn’t always been possible. He doesn’t know that you weren’t always able to explore the sets virtually, see them from any angle, or that you couldn’t open doors and enter rooms that never actually appeared in the original film.
Or maybe, if his attention span wavers, he’ll opt to experience the film as if shot from the POV of that baseball that McQueen keeps tossing.
