In this episode, Professor Geoffrey West and I explore complexity, scaling laws, cities, biology, and the future of humanity. We discuss what makes a system “complex” rather than simple and why physics can describe so much of the universe through elegant equations, yet still struggles to capture the messy world of organisms, cities, companies, politics, poetry, conflict, and human society. We also examine scaling laws in biology and cities: why larger animals use energy differently, why heart rate and metabolism change with size, and how similar mathematical patterns appear in urban systems. Professor West explains why bigger cities need less infrastructure per person but produce more socioeconomic activity — including more innovation, wealth, crime, and disease. Finally, we discuss sustainability, innovation, collapse, technology, AI, social change, and whether humanity can keep reinventing itself fast enough to avoid crisis. Professor West argues that technological innovation alone may only postpone collapse, and that genuine sustainability will also require deep social and political innovation.
