Ricard Solé on Liquid and Solid Brains and Terraforming The Biosphere

What does it mean to think? What are the traits of thinking systems that we could use to identify them? Different environmental variables call for different strategies in individual and collective cognition — what defines the threshold at which so-called “solid” brains transition into “liquids”? And how might we apply these and related lessons from ecology and evolution to help steward a diverse and thriving future with technology, and keep the biosphere afloat?

Welcome to COMPLEXITY, the official podcast of the Santa Fe Institute. I’m your host, Michael Garfield, and every other week we’ll bring you with us for far-ranging conversations with our worldwide network of rigorous researchers developing new frameworks to explain the deepest mysteries of the universe.

This week on the show we talk to SFI External Professor Ricard Solé of the Universitat Pompeu Fabra (Website, Twitter, Google Scholar) about liquid and solid brains, the scaling of cognition, criticality, contagions, and terraforming our own planet with synthetic bio.

Miller, and an open postdoctoral fellowship in Belief Dynamics — at santafe.edu/engage.

Lastly, join us June 19-23 for Collective Intelligence: Foundations + Radical Ideas, a first-ever event open to both academics and professionals, with sessions on adaptive matter, animal groups, brains, AI, teams, and more. Space is limited! Apps close February 1st. Learn more on our website.

Thank you for listening!
