Episode notes

The development of movement and sensors was crucial in the evolution of organisms as it required a nervous system and the integration of information, which sparked the revolution of internurals. Internurals play a key role in information processing by connecting different elements and allowing for the complexity of information processing. Organisms without internurals, like plants, face significant limitations in information processing. The invention of neurons that exclusively communicate with other neurons and process information marked a revolutionary moment in the history of evolution.

Octopuses, artificial intelligence, and advanced alien civilizations: for many reasons, it's interesting to contemplate ways of thinking other than whatever it is we humans do. How should we think about the space of all possible cognitions? One aspect is simply the physics of the underlying substrate, the physical stuff that is actually doing the thinking. We are used to brains being solid -- squishy, perhaps, but consisting of units in an essentially fixed array. What about liquid brains, where the units can move around? Would an ant colony count? We talk with complexity theorist Ricard Solé about complexity, criticality, and cognition.
