Is it okay to use ChatGPT to write a book?

Is it ethical and appropriate to utilize ChatGPT, a language model known for its generative capabilities, to pen an entire book? While the technology's prowess in producing coherent text is undeniable, does it undermine the authenticity and creativity traditionally associated with authorship? Does the use of AI in this manner compromise the integrity of literary works and potentially diminish the value of human-authored books? Furthermore, are there any legal considerations or copyright implications one should be aware of before embarking on such a project?
