Fei-Fei Li ( @drfeifei ) beautifully explains Robotics.

She defines robotics not by form, like humanoids or cars, but by function: they are any "embodied machines" that must perceive, understand, and act within a physical, 3D space.

This core requirement is "spatial intelligence," the unifying principle of all robotics, allowing them to perform tasks and even collaborate with humans.

Throughout all of human history, we have been confined to a single, shared reality: the "physical Earth 3D world."

This singularity has been our only playground.

However, new technologies that combine 3D generation and reconstruction are shattering this limitation.

We can now create "infinite universes"—a multiverse of digital worlds for countless purposes, from training robots to enabling creativity, travel, and storytelling.

This leap from one physical world to an infinite multiverse unlocks boundless possibilities for human imagination and interaction.
