Seth Lloyd, a professor of mechanical engineering at MIT and an expert in measuring complexity, dives into the challenges of quantifying complexity across various scientific fields. He discusses Kolmogorov complexity and Shannon entropy, unraveling their implications for understanding biological systems. Exploring cellular automata and effective complexity, he demonstrates how simple rules can generate complex behaviors. Lloyd also examines bacterial metabolism, network complexity, and the environmental concerns of large language models, revealing the intricate dance between order and chaos in our universe.
