Perhaps, or one could use the same AI to have any kind of book you wish. I fail to see the use of the ‘real’ author, since I doubt they could dictate the direction I’d want a book better than an AI that adjusts in real-time my preferences whenever I open up my magic book full of anything I want it to be. You’re correct, so long as we don’t have the freedom to make the book ourselves. In fact, it may be seen as limited to even buy a book except for historical or novel purposes (pun intended).
