For example in graphics all the physics of light is well understood - it's just infeasible to compute - so all advances are in CS and how to sample better.
Nitpick: The physics of light is understood. Human vision is also understood. But critically, human vision is completely overlooked in most graphical applications. It's not accurate to say that "the path toward making a computer-generated video indistinguishable from a camcorder recording is just a matter of sampling better." There will need to be a fundamental shift in the industry's thinking before realism will be achieved.
It's a fascinating topic that occupied many years of my life, though this is a bit off-topic.
