When you're in the trenches actually making code changes yourself, you get irritated and are driven towards improving the code as you implement new features. AI never does because it never has to. And because you're not in the trenches, you don't actually experience the frustration of managing the code base. So from your tactical view everything is fine, and when you're reviewing an isolated change you don't have the context of everything the AI had to read and figure out to get there. If you had to wade through shit to figure out how to implement something, you'd have made those refactors a long time ago. AI just eats it up and serves you a new plate of slop. It's a blessing and a curse depending on who you ask.

AIs greatest strength is still throwaway code.
