I've always loved animation, but I'll admit part of that comes from the hubris involved. It's pure insanity that people ever drew, by hand, mountains of individual drawings each slightly changed and assembled them into compelling illusions to tell stories. The amount of work that goes into animation is just staggering and anyone sensible would have rejected the entire concept as absurd. I wonder if animation will start losing part of its magic for me when it's done primarily by AI.
On the other hand though, another thing I've always loved about animation as a storytelling medium is that it isn't as limited by practical concerns like physics or reality. If something can be imagined, it can be drawn and animated if somebody has the skill and the resources to fund the massive amounts of work. It's time/money that forces animators to take shortcuts and make compromises. Creative decisions are made and rejected all the time due to those constraints. If AI driven animation gets more advanced to the point where that's no longer such a barrier it could create output more in line with the vision of creators and that's exciting too!
I hope that traditional hand drawn animation never dies, but I look forward to seeing how AI continues to change the industry and the output.
