In the latest episode of Moral Mayhem, we discuss Robin Hanson's essays on cultural drift -- examining whether and how global monoculture and reduced existential pressures may lead to biologically maladaptive cultural values. I've seen at least one post on this topic on LW. 

@Robin_Hanson will be joining us next week to continue this discussion. Feel free to comment with questions you'd be interested in having Hanson respond to.
