In this episode of Rethink Reality, I’m joined by Fei-Fei Li, founder of World Labs, for a wide-ranging conversation about perception, intelligence, and what it actually means to understand a world.We explore why perception and action evolved together, whether an AI can truly “see” without acting, and how world models are changing robotics, creativity, and simulation. Along the way, we talk about memory beyond the brain, common sense in machines, subjective language vs physical reality, and why 3D spatial understanding matters more than most people realize.This episode also goes deeper than technology. We discuss human dignity, ethics, ownership of powerful tools, and how creators and technologists can work together without losing what makes creativity human.It’s part philosophy, part engineering, part future-casting — and a reminder that every new tool reshapes how we see reality itself.Topics include:Perception vs action in biological and artificial systemsWhat counts as a “world” — physical, abstract, and simulatedMemory, morphology, and embodied intelligenceCommon sense and language in AIWorld models, simulation, and roboticsHuman dignity in the age of intelligent machinesGuest: Dr. Fei-Fei LiHost: Don Allen Stevenson IIICreative Technologist • AI Research Lead, AsteriaMasterClass Instructor | Ex-DreamWorks🔗 Links & ResourcesWorld Labs / MarbleExplore Marble: https://marble.worldlabs.ai/Follow & ConnectDon Allen on X: https://x.com/DonAllenIIIDon Allen on Instagram: https://www.instagram.com/donalleniiiWebsite: https://www.donalleniii.meWorld LabsX: https://x.com/theworldlabsLinkedIn: https://www.linkedin.com/company/world-labs
