In this thought-provoking conversation, biologist Michael Levin explores the frontiers of biological intelligence, challenging conventional boundaries between life and non-life, mind and matter. The discussion ventures into how cells communicate, make decisions, and collectively achieve complex goals—revealing intelligence as a distributed, scalable phenomenon across nature.
Levin presents a paradigm where intelligence is not exclusive to brains but emerges in tissues, cells, and even algorithms through goal-directed behavior and communication via bioelectric signals. He advocates for viewing biological systems as information-processing agents capable of problem-solving, illustrated by xenobots and anthrobots—synthetic living machines that self-organize, heal, and adapt without genetic modification. These systems suggest that morphology and aging are not fixed but can be reprogrammed through environmental and electrical cues. The dialogue extends to broader concepts: memories as persistent patterns surviving biological transformation, minds as emergent structures in a 'Platonic space' of forms, and the possibility that consciousness interfaces with hidden realities. Unexpected intelligence appears even in simple sorting algorithms, hinting at universal principles of agency. Levin emphasizes empirical exploration over anthropocentric assumptions, urging science to recognize diverse intelligences in biology, AI, and collective systems. Ultimately, he envisions regenerative medicine and synthetic biology advancing through high-level 'persuasion' of cellular systems rather than micromanagement.
