In this second episode, I talk to Wendell Wallach, who is a consultant, ethicist, and scholar at Yale University’s Interdisciplinary Center for Bioethics. Among many other things, Wendell co-authored (with Colin Allen) the influential Moral Machines: Teaching Robots Right From Wrong (Oxford University Press 2009), which maps the new field of machine ethics. Wallach talks about his extraordinary career, from being a spiritual guru in the 1960s to becoming one of today’s leading authorities on machine ethics. He also discusses his involvement in the transhumanist society, as well as his current project of developing a ‘silent ethics’, grounded in meditation practices.
