I think Sci-Fi books are as they are thanks to their potential for guessing problems that will come with the "progress" of science and technology, more than their level of accuracy to anticipate details about innovations in the future. From that point of view, Bradbury was a master of Sci-Fi when wrote this book, sixty years later, is evident that most of the humanity is more like Mildred... But I'm not as pessimistic as Bradbury about technology in our lives, ironically, I read Fahrenheit 451 in a screen and, sometimes, with an auricular in my ear (text to speech technology). I enjoyed this book.
