That same function could be fulfilled by better search engines though, even if they don't actually write a plan for you. I think you're right about it being more available now, and perhaps that is a bad thing. But you don't need AI for that, and it would happen anyway sooner or later even with just incremental increases in our ability to find information other humans have written. (Like a version of google books that didn't limit the view to a small preview, to use your specific example of a book where this info already exists)
