Neil Postman's Amusing Ourselves To Death is still must reading, two decades after its publication. Illustrating it adds an amazing power to Postman's statements. Kudos to Ego Dialogues for the successfully making these prophecies even more contemporary. (BTW, I happen to believe both secular prophets were correct, as we're living in a weird blend of the two.)
Read the comic, then go read the book. You won't be sorry.
