## TL;DR

- AI researchers are shifting attention from chatbots to world models: systems that learn not just text, but space, time, light, motion, and the consequences of actions.

---

## Summary

- AI researchers are shifting attention from chatbots to world models: systems that learn not just text, but space, time, light, motion, and the consequences of actions.
- Louis Castricato left his LLM PhD work at Brown University and founded Overworld, a startup building interactive game worlds where characters can open doors and manipulate detailed environments.
- Fei-Fei Li, Yann LeCun, and Martial Hebert frame this as the missing layer for robots: geometry, contact, balance, and cause-and-effect cannot be learned reliably from text alone.
- The market is early and PR-heavy, but capital is moving. Kindred Ventures backs Overworld, while Causal Labs targets weather models and Extropic pursues specialized hardware.

## Nauti's Take

Nauti would stay cautiously optimistic here. The thesis is strong: intelligence without a model of bodies, objects, and consequences stays shallow. But world model is already broad enough to sell beautiful video generators, robotics simulators, and planning agents under one label. The real test is not the forest demo; it is whether a system can act reliably in changing situations without being rebuilt for every edge case.
