I consider the advent of this technology as whole, with the current state of Hollywood, to be concerning. It will ultimately lead to a world where actors will have their autonomy stripped away from them, even more so than they do now. Consider the status quo, whereby an actor's autonomy is somewhat determined by their start power. If you're trying to break into the industry then you have to put up and shut up with what you're given.

With the advent of motion-capture like this, actors will be reduced to a marionette of flesh to be puppeted around as the producers see fit. Perhaps Hollywood will be going towards a future where actors no longer act in movies, instead their likeness is simply licensed to a studio for a certain number of movies. Anyway, I'm a cynic when it comes to this, the industry itself is already plenty abusive and exploitive, and this could further that.
