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.
I think we'll have to agree to disagree about well done 3D renders not feeling real. Movie studios still regularly underplay how much CGI they use for marketing purposes, and get away with it, because the CGI looks so utterly real that nobody even notices it until much later when the VFX vendors are allowed to give a peek behind the curtain.
e.g. Top Gun Mavericks much lauded "practical" jet shots, which were filmed on real planes, but then the pilots were isolated and composited into 100% CGI planes with the backdrops also being CGI in many cases, and huge swathes of viewers and press bought the marketing line that what they saw was all practical.
