Another very good EconTalk episode hosted by Russ Roberts is this one from early 2013 with Kevin Kelly of Wired fame. It was prompted by the writer’s article for the magazine “Better Than Human” (a title not of his choosing nor his liking). Most interesting to me was Kelly’s idea that this century is one of identity crisis for our species, that the things we thought we were meant to do (chess, manufacturing, etc.) have been taken from our domain, so we’ll have to figure out what our role should be, reassess what our purpose truly is.
