Melanie - I think you've just predicted where live "acting" will go : reality shows. The so-called spontaneous performances in these are already suggested (read : type-cast and coached) and edited to a remarkable degree. They just don't have professional training in what they do - yet. Film actors as we know them will become part of character creation teams. Well, actually they already ARE part of character creation teams - they will just have to accept that they provide less of the "input", such as mime and audio, and no longer the visuals. "Their" visual input is already only part of a team effort (involving stylist, lights/camera man and director etc.) There will still be a good market for the right skills - who wouldn't want Robin Williams to provide audio for one's own CG production? It will just eliminate the "star system" that pours $$$ into the egos/bank accounts of all the Give-me Moores of present Hollywood. If some of all those $$$ could be poured into actual filmmaking instead (especially into CG, with its potential doubling every sixteen months by Moore's Law), I think we'd have a lot more great new movies than we do now ;o)
