If you go on Amazon and search "100,000 whys", you will find page after page of essentially the exact same book. Presumably because asking some AI model "give me an idea for an educational book aimed at children" gave that answer.
I just asked ChatGPT to generate me an educational book title for children, searched the first result it gave me on Amazon, and found a book titled exactly that published a couple of months ago.
LLMs converge towards expected text which makes them really bad at creating novel interesting ideas when given essentially no information. You have to create the unique part yourself.
