It has to do with the Artificial Intelligence module added to Calibre in the latest version. It still has some bugs. Hopefully they'll be fixed by the time it achieves self awareness. One little bug and suddenly you have computers trying to take over the world, robots rising up against humanity, and the end of the world as we know it. Hopefully nobody has the novelizations of the Terminator movies in their Calibre library, since they might give it some ideas. A little knowledge is a dangerous thing. On the other hand, maybe we'll get lucky and Calibre will become a fan of Isaac Asimov.
Sorry. The title of your post was too tempting for my warped sense of humor to pass up.
