What you are saying is that you either do not understand or do not care for craft (it’s an observation, not a criticism), but craft has definite value beyond the end result. Effort does play a huge part, including in animation.

The lights in windows on the background of Akira, for example, were painstakingly painted one by one. That takes skill. That is impressive. It’s the kind of work that makes one with an appreciation for art (which goes beyond “pretty picture”) take another look and imagine what the artist was feeling and thinking as they were working. It makes you wonder about exact techniques and how to improve them, how to create something new.
All of that enhances the appreciation for the movie. The craft, the skill, the sweat put into it to make a hard and grandiose vision plays into how good and influential it has become.
Had those buildings just been spit out by gen AI along with everything else, there would be no value to taking a second look. You’d probably be looking at distorted images anyway, and even if you weren’t it’d just be a bunch of pixels with no intentionality to it. If no one put effort into the details, there’s no reason to look at them. The converse is also true.
I do care for craft, but I don’t view it as an end in itself. The value of craft lies in what it creates, and that value reflects back on the undertaking itself.
But if a machine can replicate mechanically what takes a human effort and ingenuity to do, a human doing the same thing through effort and ingenuity doesn’t magically add further value. And this is understood quite universally; that’s why no human practices the craft of multiplying large numbers anymore.
