Levin argues that intelligence and mind exist on a continuum across all biological systems—from cells to organisms to potentially artificial systems—and that traditional physics-based approaches are insufficient for understanding life. He presents a "technological approach to mind everywhere" that treats cognition as a spectrum of persuadability, with practical applications in regenerative medicine, aging, and communication with unconventional intelligences.

Key takeaways
  • Intelligence should be measured by "persuadability"—how much a system can be reprogrammed or convinced to pursue different goals—rather than assuming fixed categories like "living" vs. "non-living."
  • The cognitive light cone (the scale of the biggest goal a system can actively pursue) is the fundamental unit for comparing minds across different embodiments, from bacteria with micron-scale goals to humans with multi-generational aspirations.
  • Open-loop models (like cellular automata) cannot explain morphogenesis and development; biological systems navigate goal spaces and adjust their behavior when barriers block their objectives, demonstrating active agency even at the cellular level.
  • Bioelectric patterns appear to encode anatomical goal states that can be read, visualized, and rewritten—offering new therapeutic approaches to aging, cancer, and regeneration without genetic modification.
  • The distinction between software and hardware, or patterns and physical substrate, is not fundamental; which is the "agent" and which the "excitable medium" depends on the research question and perspective chosen.
  • Xenobots and anthropods—novel synthetic organisms created from frog and human cells—demonstrate that cells have capacities far beyond their evolutionary history when liberated from organismal constraints, revealing unknown cognitive properties.
