World models could revolutionize robotics and gaming, as AI moves beyond text to understand real-world dynamics. These models help AI grasp how things move and interact, making robots and virtual environments smarter. Experts Fei-Fei Li and Yann LeCun say this shift could change everything from robotics to immersive gaming. Fei-Fei Li explains world models come in three flavors: renderers, simulators, and planners. Planners let robots handle messy, unpredictable spaces, eliminating reliance on perfect setups. Startups like Overworld are building game worlds that react to players in real time, while Extropic creates hardware for these advanced AIs and Causal Labs builds AI models. Investors are betting this tech is the next big thing.
