🧾 EPISODE SUMMARY

In this episode of Lex Fridman Podcast, featuring Lex Fridman and Dileep George, Dileep George: Brain-Inspired AI | Lex Fridman Podcast #115 explores dileep George explains brain-inspired AI, inference, and human-like vision Lex Fridman and Dileep George explore how insights from neuroscience can guide the design of artificial intelligence, focusing especially on perception and vision. George critiques brute‑force brain simulations like Blue Brain and instead advocates for explicit computational theories that explain how neural microcircuits implement inference and world modeling. He describes his Recursive Cortical Network (RCN), a brain‑inspired vision system that uses feedback, lateral connections, and probabilistic inference to solve tasks like CAPTCHAs with very little training data. The conversation broadens to concept learning, grounded language understanding, memory, GPT‑style large language models, brain–computer interfaces, and what it really means to “understand” the brain if our goal is to build AGI.
