Spent Two Hours Debugging What Ai Wrote In Four Seconds

asked an AI to write code for me today it did it in four seconds looked clean compiled fine seemed legit and then i spent the next two hours figuring out why it was subtly catastrophically wrong in a way that would have only shown up in prod at 2am on a Friday with a client screaming on the other end so yeah that's the job now it's not about who can write the most lines it's about who knows enough to look at four seconds of confident AI output and go wait something is off here before that becomes a four week incident report and a very uncomfortable retrospective generative AI didn't replace thinking it just made thinking the only thing that actually matters now because the code is free the judgment is not.
