I love this conversation and most (or all) those made by Lex and his guests, but there is one sentence that should scare the hell out of us anytime we hear it (and often we hear it from researchers and engineers; I'm a scientist and technologist myself): "we need/should/must change human behavior". <br>For Leibnitz's God's sake, human behavior will NOT change, because it is the product of millions of years of evolution of humanoids on top of 200 (two hundred) millions of evolution of mammals. BUT, if we start doing things and building institutions around the idea of changing human behavior, the only possible outcome is crossing the deadline into totalitarian and abolishing freedom and humanity. <br>This is NOT what we need to aim to. Instead we should aim at expanding the intellectual and social capabilities of ourselves, so that we develop civilization into becoming better than we are. And this would not be anything close to "changing" our behavior but building on top of it, and making the best out of it.
