It is currently not possible for an AI to write a novel that humans won't know has been written by a machine itself. AI writing tools are capable of generating human-like text, but they have limitations in understanding context, tone, and nuance, which are crucial elements in creative writing. AI also lacks originality and creativity, which are essential in producing a literary work that resonates with human readers. While AI can assist authors in the writing process, it cannot replace human creativity and emotional engagement. Therefore, it is unlikely that an AI-written novel will be able to match the complexity, depth, and emotional impact of a novel written by a human author.
