What if one model could realistically predict the economy of an entire country? The entire world? A month-long working group, co-organized by SFI External Professor @doynefarmer.bsky.social, made the case that agent-based models may bring this vision to life:

How to improve LLM responses in domains we can’t score? Implicit signals from structured dialogue help LLM agents edit their own contexts, improving responses dramatically. “Self-evolving expertise in complex non-verifiable subject domains: dialogue as implicit meta-RL”. arxiv.org/pdf/2510.15772

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!

The #EnergyTransition is unstoppable and is going to happen much faster than people think. This is not a linear transition - it's happening at an exponential rate. The data indicates that half of all global energy will be renewable by the mid-2030s
