This happened to me too (almost subconsciously I might add). I'm actually not anti-AI at all, maybe a bit uninterested in AI-made art, since I don't fully see much use for it except for generating fun pictures of Golden Retriever dogs in silly situations, but this imitation-Ghibli art style is probably one of the least pleasing things to my eye that people love making. It's so round and without edge, it's colors are washed out in a very non-offensive way, and also it does not even look like the source material.
I wouldn't be so aggrieved by it, I think, if there wasn't that wave where everyone and their dog was making pictures in that style. Sorry, just a small rant tangentially related to the article, which is fine. :)
