This short is a work of art with an honest message. All that magnificent machinery is the work of human minds and hands--as is the animation, itself--and without the tender loving care of the machinery's creators and maintainers, the machinery eventually fails to function. The other thing about the machinery is that it is designed specifically for the benefit of humans, whether it's to manufacture products humans demand to make their lives better or the products, themselves, being manufactured. Those machines were designed to serve humans, but if there are no humans to serve, what's the point to their existence?
I have no criticisms about this piece. It's visually striking, with clean animation and a solid music score. I hope this team stays together to do more work of this caliber.
