Episode notes
Persuadability Over Binary Minds
- Persuadability is an engineering lens: systems sit on a spectrum of how easily they can be guided rather than a binary mind/mechanism split.
- Use interaction protocols (training, incentives, interfaces) to discover what tools can steer a system.
No Sharp Line Between Life And Nonlife
- Levin rejects a sharp living/nonliving line and argues for a continuum of competence and agency.
- Focus on transformation and scaling processes rather than searching for a single origin moment.
Cognitive Light Cone Explains Agency Scale
- Cognitive light cone measures the largest goal an agent can pursue across space-time and scales with intelligence.
- Life aligns parts so the collective light cone exceeds that of individual components.
