While there are valid reasons to fear both the "Orwell dystopia" and the "Huxley dystopia", the former tends to send more of a chill down my spine. I think this is because it seems much more possible, on a personal level, to resist or opt out of the Huxley dystopia than the Orwell one. Postman may have a compelling point that much of it has happened already, but it has happened through individual choices that I don't have to share -- the books are still there to be read, the tools & techniques are there to filter the information overload & focus on the good stuff. Admittedly this is not easy, but in the Orwell dystopia it's not even a possibility.

disclaimer: I haven't read the book and am responding to the (likely oversimplified) line of argument presented in the comic.
