Fei-Fei Li vs. Yann LeCun on world models: one is selling tools, the other is betting on science

Deep Blue AI compares the approaches of Fei-Fei Li's World Labs and Yann LeCun's AMI Labs to world models: the former builds explicit 3D scenes that are geometrically consistent and can be imported into physics engines, while the latter uses JEPA to make predictions in an abstract representation space.
