Performance capture is a genre of acting which is not going to go away, it's going to proliferate more and more. I'm passionate about it, and I love it. It's the most liberating tool an actor has, because you are not limited by your own physicality, look, or color of your eyes.
Performance capture is a tool that young actors will need in the next 10, 20 years. It's on the increase, as you say. It's not going away.
