This is interesting because I recently had a conversation with a friend, who told me that chatgpt was wrong about a small detail on a very niche topic he happens to be very knowledgeable about. I trust he's right in this case, because I am well aware of AI "hallucinations"

In another instance, I was researching a specific topic with the help of ai, and got some information contradicting the premise of a book I had recently read. I made sure to double check other sources, and yes, chatgpt was right, and the book was wrong ! Can you imagine writing an Amazon 5-star rated book, and the premise of your argument is factually and demonstrably wrong, and most readers won't even know?
