Three lessons carried over directly. First, when a student fails a topic, the real cause is almost always an unmastered prerequisite several chapters back, the same way a UI bug often lives in the data layer. Concepts have dependencies, like a build graph, so I stopped organizing learning by chapter and started organizing it by concept. Second, mastery before movement is just test-driven development for humans: a concept has to pass its own tests cleanly before anything built on top of it can run, otherwise you accumulate the learning equivalent of technical debt. Third, real adaptive pacing is a job queue, not a difficulty slider, and it only works if your input signal is honest, which is why school report cards are useless and a separate clean assessment layer is essential. On AI: it is excellent at generating practice problems and explanations, but terrible at judging whether a student genuinely understands, so the component that generates and the component that verifies...","thumbnail_url":"https://img.transistorcdn.com/vaJCR33NmQk8HOQR9bxYDTNQcTfTHvt9Ml9t7wud3WI/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9zaG93/LzQxMjc0LzE2ODM1/ODIzOTctYXJ0d29y/ay5qcGc.webp","thumbnail_width":300,"thumbnail_height":300}
