I'm not sure that's true. I researched a topic then asked ChatGPT to write an article as an experiment.
The first draft had some egregious errors, such as putting the subject's birthplace in Ireland, not Wales.
When challenged it checked, apologised and corrected the error.
I've since had a conversation with someone who has been using ai a lot partly through their studies. He recommends starting with a short, clear brief. Then a process of review and refinement; not using the AI as a substitute for learning, but a tool for gathering, organising and presenting information. To be effective a tool has to be wielded by a skilled hand.
