It might be more comfy for HN/engineering types if all book titles were completely dry and precise like that, but most 'real' people enjoy a bit of hyperbole, and have no trouble seeing straight through it. It's all part of a game that helps engage them, and they are willing participants in that game – if you can't differentiate this from deception, it's you who has an incomplete picture of things. To most people, the fact that the title "4 hour work week" is a bit of attention-grabbing hyperbole is completely obvious, including those who actually read it and got some value from it. If you think anyone who reads a book like that must be some kind of idiot who takes a literal interpretation of an obviously hyperbolic title, then you probably have a cynical and incomplete understanding of how smart most people are. The truth is, identifying the most literal possible description for something is usually just an aspy trick we engineers like to pull when we are confused by something nuanced.
