Interesting, and readable. Felt quite dumbed down and repetitive.

While there's no rule saying things can't be simple, this felt like an incredibly binary take on an aspect of an incredibly complex system.

I enjoyed some of the stories about dopamine, and the reward prediction error stuff was really interesting (and something that I'm noticing now it has been pointed out)

Overall it just felt a bit dated in approach, and almost like astrology in some of the conclusions.
