CG will expand opportunities for good actors, not reduce them. If you've ever tried to record your own dialogue for an animation you begin to appreciate what serious talent it takes to bring a character to life! We might not understand what it takes, but we all know it when we see it, and when we don't see it. What CG means is that gifted voice actors who don't fit the physical or age requirements of a role will be able to give voice and provide mocap of all those subtle bits of business that make up a truely professional, satisfying performance.
