Why would someone only ask an LLM questions when they were in the market to buy a book? Most people I know don't buy books in order to look up the answer to a question, sure some people buy reference books and use them but that's not really what we think of when talking about authors and books. If I'm in the market for a book, I'm looking to read a book, not query something or someone for answers. I think your example should go like this:
Tomorrow: 1) you do research, write posts, publish a book, 2) it is all consumed by a for-profit operated LLM. 3) People ask LLM to get answers to some related question or interest 4) They ask the LLM for a list of recent books that go in depth on the topic or are in the genre etc. 5) Your name comes up in the list 6) Goto step 2 from Yesterday
