Animation is the weakest area in VFX - Intro

I read an article about the future of VFX a long time ago. It was in 2004. You can still have it:12 Predictions on the Future of VFX. We can summarize what came true.
My point is as the title says: the animation in VFX is still way more immature than other areas. I don't speak about animated (2D or CG) films or shorts because they are amazing.
It is a complex issue. First of all I should define what I mean by animation. Usually we can separate animation of living things like animals (not plants though) and the others. We can talk about keyframe animation, technical animation, traditional animation, character animation, etc.
I want to write about it in details, but right now I just post a video. It is about how science can deal with animation. I'm looking forward to the solution where animation is kind of a mixture of simulation and keyframe animation.
