A key finding that the judge said in the Authors Guild v. Google case was that the authors benefited from the tool that google created. A search tool is not a replacement for a book, and are much more likely to generate awareness of the book which in turn should increase sales for the author.

AI platforms that replaces and directly compete with authors can not use the same argument. If anything, those suing AI platforms are more likely to bring up Authors Guild v. Google as a guiding case to determine when to apply fair use.
