The point is because it generally produces crap code you have to one shot or else iteration becomes hard. Similar to how a junior would try to refactor their mess and just make a bigger mess

I find it hard to believe that when the AI generates crap code, there is absolutely nothing you can do (change the prompt, modify context, add examples) to make it do what you want. It has not been my experience either. I only use AI to make small modules and refactor instead of one-shoting.

Also I find "AI makes crap code so we should give it a bigger task" illogical.
