Drawing a parallel to the Cambrian Explosion, where vision evolved alongside nervous systems, Dr. Li argues that perception's primary purpose is to enable action and interaction. This principle suggests that for AI to advance, particularly in robotics, computer vision must be developed as the foundation for embodied intelligence, not just for classification.

While LLMs dominate headlines, Dr. Fei-Fei Li argues that "spatial intelligence"—the ability to understand and interact with the 3D world—is the critical, underappreciated next step for AI. This capability is the linchpin for unlocking meaningful advances in robotics, design, and manufacturing.
Language is just one 'keyhole' into intelligence. True artificial general intelligence (AGI) requires 'world modeling'—a spatial intelligence that understands geometry, physics, and actions. This capability to represent and interact with the state of the world is the next critical phase of AI development beyond current language models.
Large language models are insufficient for tasks requiring real-world interaction and spatial understanding, like robotics or disaster response. World models provide this missing piece by generating interactive, reason-able 3D environments. They represent a foundational shift from language-based AI to a more holistic, spatially intelligent AI.
GI's founder argues game footage is a superior data source for spatial reasoning compared to real-world videos. Gaming directly links visual perception to hand-eye motor control ("simulating optical dynamics with your hand"), avoiding the information loss inherent in interpreting passive video, which requires solving for pose estimation and inverse dynamics.
Dr. Fei-Fei Li cites the deduction of DNA's double-helix structure as a prime example of a cognitive leap that required deep spatial and geometric reasoning—a feat impossible with language alone. This illustrates that future AI systems will need world-modeling capabilities to achieve similar breakthroughs and augment human scientific discovery.
World Labs co-founder Fei-Fei Li posits that spatial intelligence—the ability to reason and interact in 3D space—is a distinct and complementary form of intelligence to language. This capability is essential for tasks like robotic manipulation and scientific discovery that cannot be reduced to linguistic descriptions.
AR and robotics are bottlenecked by software's inability to truly understand the 3D world. Spatial intelligence is positioned as the fundamental operating system that connects a device's digital "brain" to physical reality. This layer is crucial for enabling meaningful interaction and maturing the hardware platforms.
Human intelligence is multifaceted. While LLMs excel at linguistic intelligence, they lack spatial intelligence—the ability to understand, reason, and interact within a 3D world. This capability, crucial for tasks from robotics to scientific discovery, is the focus for the next wave of AI models.
Dr. Fei-Fei Li warns that the current AI discourse is dangerously tech-centric, overlooking its human core. She argues the conversation must shift to how AI is made by, impacts, and should be governed by people, with a focus on preserving human dignity and agency amidst rapid technological change.
Classical robots required expensive, rigid, and precise hardware because they were blind. Modern AI perception acts as 'eyes', allowing robots to correct for inaccuracies in real-time. This enables the use of cheaper, compliant, and inherently safer mechanical components, fundamentally changing hardware design philosophy.
