To simplify even further, would it be right to say that dopamine is not just a carrot being used to adjust weights but that the entire dopamine system actively learns how/when/why to use the carrot to effectively train? if so, some interesting real world parallels i can see: 1/ this is why good teachers early on have such a profound effect. Teachers act as a dopamine system so good teachers teach meta learning via whatever they teach 2/ teaching the meta directly is difficult as the meta of the meta is too abstract. Which is why grammar/math may tend to feel out of touch. They are already the meta. 3/ drugs can mess up the dopamine system and throw the feedback loop out of whack. Even if you have the best resources, the “teacher” is now inept
