“Can computers become conscious?”: My reply to Roger Penrose
Posted by Dan Breeden in categories: computing, quantum physics
A few weeks ago, I attended the Seven Pines Symposium on Fundamental Problems in Physics outside Minneapolis, where I had the honor of participating in a panel discussion with Sir Roger Penrose. The way it worked was, Penrose spoke for a half hour about his ideas about conscious ness (Gödel, quantum gravity, microtubules, uncomputability, you know the drill), then I delivered a half-hour “response,” and then there was an hour of questions and discussion from the floor. Below, I’m sharing the prepared notes for my talk, as well as some very brief recollections about the discussion afterward. (Sorry, there’s no audio or video.) I unfortunately don’t have the text or transparencies for Penrose’s talk available to me, but—with one exception, which I touch on in my own talk—his talk very much followed the outlines of his famous books, The Emperor’s New Mind and Shadows of the Mind.
Admittedly, for regular readers of this blog, not much in my own talk will be new either. Apart from a few new wisecracks, almost all of the material (including the replies to Penrose) is contained in The Ghost in the Quantum Turing Machine, Could A Quantum Computer Have Subjective Experience? (my talk at IBM T. J. Watson), and Quantum Computing Since Democritus chapters 4 and 11. See also my recent answer on Quora to “What’s your take on John Searle’s Chinese room argument”?
