Reminds me of a number of post-apocalyptic future movies. What do you want to bet that the humanity is dead and only automated robots keep things running.
PostItEase, you surprise me, you had never heard of the Factory?
That's clearly the Factory and you can bet humans are waltzing around the world like nothing, while the Misters of the Factory create a lot of Yukkuri derived products through this livestock.
You don't need a post apocalyptic scenario for this, just to remember which place would be like this, The Factory.
The first major plot-breaker for that movie... Not only does it ignore thermodynamics, it's also ... ignoring thermodynamic. (This is a big thing to me). You could say you wanted a beowulf cluster of brains, I dunno. The only saving grace is that it turned out to be a complete lie, but if any of the characters knew thermodynamics, they would have realized that immediately.
To my knowledge, that shoehorned in because it was felt that people wouldn't understand the idea of a "collective consciousness" since originally thats all what the Matrix was going to be.
This made me feel warm and fuzzy inside. My only question is that- Won't the koyukkuri splatter when they drop off the stalk? Not that I'm complaining, mind you.
