George Plimpton interviews WS in The Paris Review:
INTERVIEWER: Are you worried about the future of the written word?
STYRON : Not really. I get moments of alarm. Not long ago I received in the mail a doctoral thesis entitled “Sophie’s Choice: A Jungian Perspective,” which I sat down to read. It was quite a long document. In the first paragraph it said, In this thesis my point of reference throughout will be the Alan J. Pakula movie of Sophie’s Choice. There was a footnote, which I swear to you said, Where the movie is obscure I will refer to William Styron’s novel for clarification. This idiocy laid a pall over my life for a dark brief time because it brought back all these bugaboos we have about the written word. But in the nineteenth century they said that the railroads were going to jeopardize the written word; in the 1920s they said that the appearance of sound movies was guaranteed to drive novels into purdah; then later, television. All of these means of communication have existed happily side by side and parallel with writing. I don’t think for a minute that literature is going to perish. Marshall McLuhan’s prophecy of forty years ago simply didn’t pan out. Even the Internet and the idea of the electronic book reinforces my belief—they will not threaten the written word but actually complement writing, and perhaps even ultimately enhance it.
