Accurate book recommendations - not what's popular, not something in the same genre as I've read, not by the same author I've read but something I'd actually want to read. I think the reason this hasn't been done is that (like movies and music) books are so complex that it's hard to tell what someone liked about one book or disliked about another book, so it's hard to know what other books would have that same feature. Which is why I think ML would be perfect for this - it's good at things like extracting common features, you just has to create one that can read and comprehend novels :)
