How is this different from hiring a designer, telling them "make me a website" and then waiting to see if they resolve the uncertainty into something you like or not?
I tell LLMs what to do in pretty high detail, and they do it. With LLMs I have much less variance than with coworkers.
It is different because for humans, it takes time to produce some result, while AI does it instantly. So if you tell a programmer to do X, you have a week for your adrenaline to cool off. If you tell AI, it will do it in minutes.
