And they're very bad at keeping other code good across iterations. So you might find that while they might've fixed the specific thing you asked for—in the best case scenario, assuming no hallucinations and such—they inadvertently broke something else. So this quickly becomes a game of whack-a-mole, at which point it's safer, quicker, and easier to fix it yourself. IME the chance of this happening is directly proportional to the length of the context.
