The real negative thing is that lots of artists will lose their source of income. The goal of technology is to relieve us from the burden of doing uninteresting stuff to dedicate more time to creating and learning. This so-called "AI" (it's not AI but whatever) is doing the exact opposite : taking away the creative and interesting tasks to give us more time to feed the orphan crushing machine.
You're talking about computer animation like no humans were involved, but having worked in that department I can garantee you couldn't be farther from the truth.
The only reason "AI" is thriving and being shoved down our throats in every possible products is because tech moguls see it as a way to oust these pesky artists who demand getting payed for their work and won't draw them anything for visibility (can you imagine that?). And this applies to every creative jobs btw, scenarists, photographers, animators, you name it! Even developpers are at risk here.
There is really NOTHING positive about streamlining creativity.
Well, you ´ve a point, I give you that.
But when you look back in human history and the way of science there were always changes when it comes about work and jobs. And as some jobs go, some other new come due to the new science progress. Imho there is place for AI and ppl who draw, there might be change and change won ´t stop, nevertheless ppl like you and me like it or not. It ´s human though, to have doubt about new things.
I ´m open for AI, but I understand ppl who dislike it or have concern about it, but it might be wrong to forbid ppl to post their stuff or attack them, just because ppl dislike how they do their art. It ´s nevertheless art, and art should always be free like the mind, that ´s my general opinion.
