Re: Film makers?
" As a medium that's existed for thousands of years and I dont see that form of presentation disappearing as a result of this medium."
Actually, the conventional stage production, with its proscenium arch, is a relatively recent invention. In Shakespeare's day, theatres looked like this: https://www.youtube.com/watch?v=b9uDK3xsLYk
Interaction with the audience was much more common in such theatres. Prior to the Globe and its peers, plays were performed ad-hoc in streets, squares, etc. again, with a lot more audience participation than is the norm in a modern theatre, where the audience is far more passive. So it's not so much about learning new tricks, as re-learning old ones. Of course, most blockbuster movies have degenerated into little more than a series of spectacular set-pieces with a thinly spread smear of plot inserted to keep people on the 'rails'. Never has the description of a movie as being a "rollercoaster of a ride" ever been so literally true: such films are mostly just glorified theme park rides with bells on.
That said, VR technology appears to be still in early First Person Shooter territory: look down and you won't see a simulacrum of your own body (or even something less disappointing). Hold your hands up before your face and nothing will happen either, so there is still a major disconnect. It's interesting that the only current device that doesn't suffer from that disconnect wasn't mentioned at all: Microsoft's Hololens. That's an AR device, but it does seem like the most likely to have uses beyond fully immersive entertainment.
