Fei‑Fei Li Says the Next AI Frontier Is Not Language but the World Itself

Fei‑Fei Li told the Cisco AI Summit that AI’s next major frontier is spatial intelligence: models that understand and simulate 3D physical space. Her company World Labs has produced Marble, a “world model” designed for persistent, physically consistent virtual environments with applications from robotics training to therapy, while cautioning that data scarcity and real‑world complexity make general‑purpose robots a distant prospect.
