Human code quality standards are built around the knowledge that humans prefer polished products that work consistently. You can get away without code quality in the short term, especially if you have no real competitors - to a lot of people, there just aren't any models other than Anthropic's which are particularly useful for software development. But in the long term it gets you into a poor quality trap that's often impossible to escape without starting over from scratch.

(Anthropic, of course, believes that advances in AI capability over the next few years will so radically reshape society that there's no point worrying about the long term.)
