The question was "why does it feel more real", and I answered that - because the best AI generated images today feel more real than the best 3D renders, even when they take all the compute in the world to finish. So I can imagine that trend going forward into real-time rendering as well.
I did not claim that AI-based rendering will overcome traditional methods, and have even explicitly said that this is a heavy assumption, but explained why I see it as exciting.
