Centuries later, the animals from Brave that have been experimented on by the witch have interbred, creating a large-scale population of animals slowly gaining personification and intelligence on their own. There are two progressions: the progression of the animals and the progression of artificial intelligence. The events of the following movies set up a power struggle between humans, animals, and machines. The stage for all-out war in regards to animals is set by Ratatouille, Finding Nemo, and Up, in that order. Notice I left out A Bug’s Life, but I’ll explain why later.
And then it starts getting really crazy:
By the events of the Toy Story movies, we are in the 90s until 2010. It’s been 40-50 years or so since the events of The Incredibles, giving A.I. plenty of time to develop BNL. Meanwhile, Pixar is hinting at dissatisfaction among pockets of toy civilizations. The toys rise up against Sid in the first movie. Jesse resents her owner, Emily, for abandoning her. Lotso Huggin’ Bear straight up hates humans by the third movie. Toys are obviously not satisfied with the status quo, providing a reason for why machines and objects alike are ready to take over. So, by the 2000s, the super-humans all but gone, and mankind is vulnerable. Animals, who want to rise up Planet of the Apes style, have the ability to take over, but we don’t see this happen. Also, A.I. never takes over humans by force. Why do you think that is? It’s reasonable to assume that machines did take over, just not as we expected. The machines used BNL, a faceless corporation (which are basically faceless in nature) to dominate the world, starting in the 1960s after the Omnidroid fails to defeat the Incredibles. In each of the Toy Story movies, it’s made painfully clear that sentient objects rely on humans for everything. For fulfillment and even energy. It’s hinted at that the Toys lose all life when put away in “storage” unless they are in a museum that will get them seen by humans.
This barely even scratches the surface. Just go read the whole thing. It’s some mad genius.
