Even if we got to the point where the digital humans are indistinguishable from real footage, all your realism is gonna go out the window when you encounter a bug where a character is half-clipped into a wall. Or when an animation breaks and someone is standing with a backwards bent knee, and no reaction on their face.

The idea that the ultimate endgame for video games is to have them look like a playable movie, or be a real-world simulation just seems silly to me.
