It was an honour to talk to an elder in science about time, chaos, entropy, emergence, climate change, hope, purpose and AI.

I am at New York climate week, and at a reception put on by @ember-energy.org, who does great work in promoting the green transition. I had the pleasure of riding in an all electric boat built by Flux Marine - it moved silently through the water to the Statue of Liberty and back at an amazing speed!

In Ep. 239, mathematician Doyne Farmer of Oxford University explains why conventional economic modeling has failed to anticipate the actual speed of the energy transition, and why using “complexity economics” can give us a much more accurate picture of it.
