Episode notes
World Models Aim To Encode Cause And Effect
- Yann LeCun argues LLMs mainly predict next words and are a dead end for AGI without models that learn cause and effect from sensory data.
- World models learn from video, sensors, and interactions to build internal simulations of objects, agents, and time for common-sense reasoning.
LLMs Are Powerful But Not Sufficient For Real World Tasks
- Hosts note LLMs excel but have diminishing returns when stretched beyond next-token prediction into tasks needing real-world understanding.
- Examples include game-playing deep learning and computer vision needing reinforcement-style learning distinct from LLMs.
Pen Demo Shows LLMs Lack Embodied Common Sense
- Jason recounts a demo where ChatGPT predicted a pen would fall but was proven wrong when the user's hand position prevented it.
- The clip highlights LLMs' lack of embodied common-sense from sensory feedback unlike human babies.
