I'm not trying to be a luddite, and it's all fun, but to me this seems like a particularily bad idea.
Sure, this obviously works most of the time, especially on romance novels. But the end result if actually used anywhere is that books would be either made to look as homogenic as possible, or they would be mischaracterized when being artistic in a nod to some content in the book.
Judging a book by its cover doesn't work with humans, and is a bad idea, ergo it's still a bad idea to have a machine do it
