  World Models Need Causality, Not Pretty Pixels — Christopher Manning, Moonlake
  AI
description: >-
  In 2007, Google already had a language model trained on 2 trillion tokens, the
  same order of magnitude as today's frontier models. Christopher Manning,
  Stanford professor, former director of the Stanford AI Lab and now at Moonlake
  AI, uses that as one stop in a tour of AI history. It runs from Dartmouth in
  1956 and Shakey the robot to the rise of LLMs, and it ends at his argument for
  what comes next: embodied intelligence built on simulation. Manning argues
  that generative video like Genie 3 simulates observations but has no semantics
  underneath, so it can't support planning. Moonlake takes a single photo or
  short video and builds an action-conditioned world in code, with objects you
  can pick up, open and move. It even researches objects on the web to fill in
  what the camera can't see, like the tea bags inside a closed box. A loop
  inspired by Claude Code compares renders against reality to shrink the
  sim-to-real gap, with the goal of replacing 10,000 hours of teleoperation with
  simulation. The talk ends with Q&A on gaming, ontologies, physics and
  discovery in latent space. Speaker info: X/Twitter: @chrmanning
