On Freethought Radio, Annie Laurie Gaylor and Dan Barker talk with evolutionary biologist Jerry Coyne (author of the best seller Why Evolution is True) about his new book, Faith vs. Fact: Why Science and Religion are Incompatible. Then we hear excerpts of Chris Johnson’s new film, A Better Life: An Exploration of Joy & Meaning in a World Without God. After that, Gordon Bonnet has some thoughts about detoxification: about when it’s necessary and when it’s just, well, woo, as in activated charcoal lemonade…yum. Then, a topic we touched on a few weeks back: the future of artificial intelligence and whether we should worry about a robot apocalypse or singularity when machines become smarter than we. First Sam Harris weighs in from his “Ask Me Anything” podcast and provides some reasons why he takes this issue very seriously and then Philosopher David Chalmers discusses the philosophical implications of the singularity with Nigel Warburton on the Philosophy Bites podcast. Finally on Point of Inquiry, host Josh Zepps interviews Alex Garland, writer and director of Ex Machina, a new film, now in theaters, that tells the story of a billionaire programmer who creates an artificially intelligent female robot. They discuss the science and philosophy behind consciousness, the future of self-aware machines, and ethical considerations we’ve barely begun to ponder.
