>emergent phenomena in complex systems Emergent phenomena in complex systems are not necessarily quantum. Weather, population dynamics, neural networks, chaotic systems can all be described with good'ol lagrangian mechanics. Other phenomena like certain phase transitions or spin glasses cannot. But what's the economic correspondence to those? Overall I agree with you. Economics should be described with the math and physics of complex systems. Unfortunately data is poor, the math is hard, the psychology is complex. So we're not quite there yet.
