World Models and the Future of Spatial AI with Justin Johnson - #775
World Labs' Marble system generates navigable 3D worlds from images with no established recipe yet
World Labs co-founder Justin Johnson outlines the emerging field of spatial AI, where models go beyond language to understand and simulate physical environments. The company's Marble system can generate navigable 3D worlds from images, but Johnson acknowledges there is still no established recipe for building world models. The long-term vision targets agents and robots that can operate in the physical world, making this a key frontier to watch as AI moves beyond text and image generation.
