With AI, as we currently understand it, we may have stumbled upon being able to replicate a part of the layer of our brain that provides the "reason" in humans., and a very specific type of "reason" a that.

All life has intelligence. Anyone who has spent a lot of time with animals, especially a lot of time with a specific animal, knows that they have a sense of self, that they are intelligent, that they have unique personalities, that they enjoy being alive, that they form bonds, that they have desires and wants, that they can be happy, excited, scared, sad. They can react with anger, surprise, gentleness, compassion. They are conscious, like us.

Humans seem to have this extra layer that I will loosely call "reasoning", which has given us an advantage over all other species, and has given some of us an advantage over the majority of the rest of us.

It is truly a scary thing that AI has only this "reasoning", and none of the other characteristics that all animals have.

Kurt Vonnegut's Galapagos and Peter Watts Blindsight have different, but very interesting takes on this concept. One postulates that our reasoning, our "big brains" is going to be our downfall, while the other postulates that reasoning is what will drive evolution and that everything else just causes inefficiencies and will cause our downfall.
