I think that “books don’t work” isn’t a precise enough statement.Take Thinking Fast and Slow, personally I found the book difficult to read because while the content is interesting the writing itself isn’t compatible . Maybe because of the genre or intended audience but the book in itself isn’t a good choice to learn about it’s content (Judgment under uncertainty, biases …)
I see it this way, to learn about a specific subject I select and skim several textbooks choose the smaller one in number of pages (more on this later) and work trough it on the span of weeks (note taking, trying to understand every part and reflect on where it comes from and so on...)
Books like Thinking Fast and Slow I read on a casual basis (commute/coffee/meals) my goal isn’t necessarily to understand everything but more like high-lighting passages of interests, important statements etc...
Michael Nielsen text for example about Neural Networks I worked trough it in textbook fashion it has interactive mediums to give an intuitive feel but still it required a bit of thinking and reflexion.
I don’t think the medium is the issue here.
 I’d describe it as heavy on the prose or writing I don’t have the exact words :(
