I agree. But people aren't making art in a style they love, people are telling a machine to make an inferior copy of something resembling art in a style they claim to love.
I say "claim to" because I find it hard to believe someone could be a fan of Ghibli and treat the studio's work in a way that Miyazaki would despise. This isn't love so much as exploitation.
If people value the Ghibli style so much, they could learn the art of drawing and animation, and actually make art instead of insulting the studio's talent and legacy by avoiding the craft and seeking an endorphine high from AI slop. It doesn't have to be perfect or even good to be satisfying, but it will be yours.
