Is it legal to sell a book written by ChatGPT?

Excuse me, could you clarify for me if the legality of selling a book written by ChatGPT is indeed unambiguous? Given the complexities surrounding artificial intelligence and intellectual property, I'm wondering if there are any potential legal grey areas or restrictions one should be aware of before embarking on such a venture. Would the legality differ based on the jurisdiction or specific content of the book? Additionally, how does one go about ensuring they have the proper rights to sell such a work, considering ChatGPT's status as an AI-generated entity? I'd appreciate any insights you could provide on this matter.
