All the world’s a robot-staging ground for tech entrepreneurs building ‘physical AI’

AI researchers are shifting focus from language models to 'world models' that enable physical AI systems to navigate real-world environments. Entrepreneurs like Louis Castricato (Overworld) and Fei-Fei Li (World Labs) are developing AI capable of understanding spatial and temporal dynamics, while Yann LeCun (Advanced Machine Intelligence Labs) emphasizes predicting action consequences. This movement aims to move beyond text-based AI to robots and interactive applications.
