So in things like this I typically hold the view of judging something based on the final product regardless of how it was made.
But every time I realize something's AI, even if it looks good, it feels like all the color and depth has been sucked out. Like realizing it has no soul, that I'm staring at a husk.
To put it in more technical terms, the realization immediately halts any deeper analysis and appreciation for the work. The question of "What meaning does this background detail has?" always has the same answer of "It was the most probable filler for that area".
It made me truly realize how much I took for granted that every part of a human art piece has a story behind it, whether intentional or not.
(sorry for the low quality image, despite seeing it a lot on Reddit this was the best one I could find online)
