J. Kim Murphy Christopher Nolan expressed caution about artificial intelligence after a special screening of “Oppenheimer,” drawing a comparison between the rapidly developing technology and his new dramatic feature about the creation of the atomic bomb. Nolan’s remarks came during a conversation following a preview screening of “Oppenheimer” in New York. Moderated by “Meet the Press” anchor Chuck Todd, the panel included Nolan, as well as Los Alamos National Laboratory director Dr. Thom Mason, physicists Dr. Carlo Rovelli and Dr. Kip Thorne, plus author Kai Bird, who co-wrote “American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer,” which Nolan’s film is based on.
