The central thesis is broadening the definition of homeostasis to fit one more layer of biological marvel after another, until the concept is so amorphous and generic that pretty much anything can go into the pile. Like many other pop-sci books that came before, the strategy is simple: incrementally build the one true hammer, and nail all the screws the world has to offer.

Halfway through the book, homeostasis is already completely dissociated from what it's supposed to mean when described by a proper science communicator. Armed with the confidence of a bestselling author, Damasio arrives at the ultimate conclusion: life doesn't follow algorithms and artificial intelligence is condemned to be a lower form.

An irrelevant hill to die on because "algorithm" and "artificial intelligence" are as vague as the concept of homeostasis crafted throughout the book. It's pointless to argue that an irresistible force is impossible because there's an immovable object out there.
