The argument is that reading and reasoning about code matters more than memorizing syntax now that AI generates much of it, since AI can produce code that looks clean but mishandles edge cases, error paths, state, or architecture. The video is sponsored by CodeRabbit, a PR review tool that reorganizes diffs into dependency-ordered groups with AI summaries. ## Full article daily.dev links to this article rather than hosting it.

Generated code is usually correct on the happy path and vague about what happens when the third call fails halfway through - and a partially applied side effect is not visible in the diff at all, it is visible in the database at 3am. State belongs in the same group: the model has no idea what else is reading the thing it just mutated.
