"Any human with above room temperature IQ can design a utopia. The reason our current system isn’t a utopia is that it wasn’t designed by humans. Just as you can look at an arid terrain and determine what shape a river will one day take by assuming water will obey gravity, so you can look at a civilization and determine what shape its institutions will one day take by assuming people will obey incentives."
