If you put Stable Diffusion or chatGPT to generate automatically without human review or prompting, they will generate tons of garbage. Generative AIs are garbage until someone stamps their work as good. So they need humans to be worth anything. They are just junk on their own. It's a long way off from job replacement - even self driving cars require human at the wheel. These AIs still hallucinate facts, who can use them as they are now. Clearly someone will have to find a way before they can get useful without being babysitted.
