I guess we'll have to wait and see. I would vote for a mix of the living and the digital, but I would hate to see live actors disappear. I just saw a production of "Midsummer's Night Dream" in which one character slid off the back of the stage (it was at an outdoor theater over a canyon). The very impressive part was that (a) the slide was an accident and yet the entire cast managed to continue along as if it was meant to happen and (b) the actor (unhurt, fortunately) managed to return to the stage without missing a beat. There will be no accidents (other than power failure) in an all digital world, nor will we see the amazing inventiveness of humans overcoming little obstacles like falling down. What makes digital people so boring is that they are too perfect. They don't have to adjust to situations. They just plod through without emotion to the next scene. Thanks but no thanks. There is a joy to the perseverance of the human spirit that no digi guy or gal will ever have. And I hope I can always tell who is real and who is not. One bleeds. The other bleeps.
