I spent some time with my kid trying to get ChatGPT 4 to write bedtime stories. We found that it kept devolving into the pattern of a generic but acceptable setup followed by something like "and then the heroes solved a variety of challenges, learning together and having fun all the way" that completely skips the meat of the story. We also noticed that it was difficult to goad the AI into adding any quotations; the characters rarely _say_ anything.
