Passive income: YES

Writing books with AI technology can potentially lead to passive income once the initial setup is done. The setup costs range from $100 to $500, mostly for purchasing AI software or tools. Creating a system for automated book generation can help in making the process more passive. While some individuals have reported success in earning passive income through this method, it is more common for only a few outliers to achieve significant passive income. It realistically becomes passive for those who invest time in setting up efficient automation and have a strategy for book promotion. Misleading expectations include thinking that passive income will come quickly or without ongoing effort. Overall, while passive income is possible with writing books using AI, it requires dedication and strategic planning to reach that level.
