On this hour of Modern Notion Daily, our guest is Wendell Wallach, an ethicist, consultant, and scholar at Yale University’s Interdisciplinary Center for Bioethics, and the author of A Dangerous Master: How to Keep Technology from Slipping Beyond Our Control (Basic Books, June 2015). Wallach thinks that technology, if it goes unchecked, could pose serious threats to humanity in the near future. His book describes ways we can counteract that possibility or prevent machines from taking over. Later in the hour, contributing editor Mark Hay tells us about ayahuasca, an not-so-new hallucinogen that’s trending. (Even Lindsay Lohan reportedly uses it.)
