Earth in Robot Hands
CK: I’m reading “The Story of CO2 Is the Story of Everything: A Planetary Experiment” by Peter Brannen. I’m only on chapter two but his thesis is clear and succinctly expressed in the title. In his view life arose to relieve the excessive gradients found on Earth. He views life as nano-engines that reduce CO2 to create temporary structure by hastening the journey to equilibrium. Life is fundamentally dissipative, and broadly comparable to burning. GPT: That places Brannen squarely in the thermodynamic tradition associated with people like Ilya Prigogine, Jeremy England, and to some extent Ludwig Boltzmann. The core intuition is that life is not an exception to the second law of thermodynamics but one of its most elaborate expressions. The key move is reframing “negative entropy.” Organisms locally build order, yes, but only by increasing total entropy production in their surroundings. A tree creates highly ordered wood and leaves, but only by accelerating solar energy degradation...
