JUDY WOODRUFF: Next: The promise and peril of the internet is the subject of Werner Herzog's new documentary out today. The legendary filmmaker was recently honored with an achievement award from the American Film Institute for his work in documentary film. In Washington, Jeffrey Brown caught up with Herzog to discuss the new film and more. WERNER HERZOG, Documentarian/Filmmaker: This is the birthplace of the internet. JEFFREY BROWN: In his new documentary, "Lo and Behold: Reveries of the Connected World," filmmaker Werner Herzog is again asking big questions.

To make a documentary about the Internet requires nerve. To do so when you can hardly be bothered with a cell phone, however, takes both innocence and bravado, plus a pinch of madness. All of which means that Werner Herzog, now aged seventy-three, is right for the job, and the result is "Lo and Behold: Reveries of the Connected World." The movie is divided into ten parts, none of which could be mistaken for a commandment; Herzog's documentaries have always been fired more by marvelling, and by an explorer's ache to learn, than by any pedagogic urge to tell. If he were struck color-blind tomorrow, he would instantly embark on a film about Matisse.

But when it comes to much-hyped and coming promise of artificially intelligent machines, the man at the helm of Tesla, SpaceX and SolarCity has deep concerns. In a video clip released Wednesday to Fortune magazine from German documentarian Werner Herzog's upcoming film about the Internet, Lo and Behold: Reveries of the Connected World (premiering Aug. 19), Musk is subdued as he explains how AI could pose a significant threat even if such technology isn't in the hands of dictators and criminals.
