A pretty good question was raised here for discussion. I don't have a publisher, and I plan to start writing a fiction book. I don't have enough experience writing books, because I only read them before that. Therefore, I think that a ghostwriter would be helpful to me. I do not trust artificial intelligence and am convinced that only a professional writer can present the main ideas and plot in the best way. I even found one service https://penfellow.com/fiction-ghostwriting/ and plan to use it to write or edit my book. Therefore, to answer the question, I will say that I will choose fiction ghostwriting instead of Artificial Intelligence software.
