"How to ask for it" is the most important part. As soon as you realize that you have to provide the AI with CONTEXT and clear instructions (you know, like a top-notch story card on a scrum board), the quality and assertiveness of the results increase a LOT.

Yes, it WON'T produce senior-level code for complex tasks, but it's great at tackling down junior to mid-level code generation/refactoring, with minor adjustments (just like a code review).

So, it's basically the same thing as having a freelancer jr dev at your disposal, but it can generate working code in 5 min instead of 5 hours.
