Valenti's magical DRM thinking debunked

Ed Felten picks apart Jack Valenti's Engadget interview (in which Valenti compares himself to JFK: "I was in Dallas in the motorcade on Nov. 22, 1963, and I saw that day a brave young president murdered, and a new president take over. The president is dead, long live the president, the nation goes on. No one is indispensable, I learned that day in Dallas. My successor will come into this job and he won't be me, but he might do a hell of a lot better job than I'm doing.")

It may be possible to so infect a movie with some kind of circuitry that allows people to copy to their heart's content, but the copied result would come out with decayed fidelity with respect to sound and color. Another would be to have some kind of design in a movie that would say, 'copy never,' 'copy once.'

Even ignoring the technical non sequiturs ("stuff … algorithms into a movie"; "infect a movie with … circuitry"), this is wildly implausible. Nothing has happened to make the technical prospects for DRM (anti-copying) technology any less bleak.

We can only hope Valenti's successor stops believing in "technological magic" and instead teaches the industry to accept technical reality. File sharing cannot be wished away. The industry needs to figure out how to deal with it.
