In an angry, polarized world, it’s good to remember the many benefits of a good laugh. Chris Duffy is a comedian and host of TED’s podcast “How to Be a Better Human,” and he joins host Krys Boyd to discuss the link between humor and innovation, how social bonds are formed over jokes and chuckles, and why humor is a key to a happy, healthy life. His book is “Humor Me: How Laughing More Can Make You Present, Creative, Connected, and Happy.”

A.I. is changing the way business is done in every industry — including the business of sex. Avantika Chilkoti, Global Business Correspondent for The Economist, joins host Krys Boyd to discuss how A.I. is affecting the pornography industry, which brings in billions of dollars annually, and to ponder whether computer-generated content will put human sex workers out of a job. Her article is “A.I. is upending the porn industry.”

There’s a fine line between a voracious hobby and an out-and-out obsession. David Greene, journalist, author and former host of NPR's Morning Edition, joins host Krys Boyd to discuss his dive into people’s personal obsessions, what drives us to latch on and grow certain fascinations and why so often these have nothing to do with the ways we make a living. His podcast is “David Greene is Obsessed” from Campside Media.
