李飞飞讲机器人本质，清晰又启发
李飞飞在a16z视频中定义机器人不是按人形或汽车等形态，而是按功能：任何必须在物理3D空间中感知、理解并行动的“具身机器”。她提出“空间智能”是机器人的统一原则，使机器人能执行任务并与人类协作。她指出人类一直局限于单一物理地球3D世界，但结合3D生成与重建的新技术正在打破这一限制，创造出无限数字宇宙，可用于训练机器人、激发创造力、旅行和叙事。

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.
