There are a definitely few ulcer-inducing events in my past that would've taken me an afternoon to fix with a current SOTA LLM vs 2+ weeks of swearing, crying and stressing out.
It will usually home right in on the bug, or will give me a good starting point.
It's also really good at letting me know if this behavior is a "commonly encountered" one, with a summary of ways it's addressed.
I've probably done that at least a dozen times, today. I guess I'm a rotten programmer.
Then I wait, look through the plan and tell it to implement and go do something else.
After a while I check the diffs and go "huh, yea, that's how I would've done it too", commit and push.
Their solution usually benefits from some simplification.
