gwern points this out in his essay, Culture Is Not About Esthetics [1]. He points that even if he read only the books that won awards, there would still be far too many to finish in his lifetime. Given that, it is no crime to ignore recent books, and, in fact, it may be better for us to stop publishing new literary works and concentrate on better appreciating the old masters.
