Sergey Levine - Building LLMs for the Physical World - [Invest Like the Best, EP.465]
Invest Like the Best with Patrick O'Shaughnessy
The Bitter Lesson Meets Physical Reality
Sergey Levine reviews debates over end-to-end learning, simulation, compositional generalization, and why caregiving tasks may be among the last solved.
My guest today is Sergey Levine, a professor at UC Berkeley and co-founder of Physical Intelligence. The company is building robotic foundation models designed to control any embodied system to do any task in any environment.
Sergey argues that solving robotics at full generality is the right path, and that building systems that learn across many robots, environments, and tasks may be the more scalable approach than building narrow specialists. We discuss how these models can perform new tasks without being trained on them directly, and why everyday human actions remain the hardest problems in the field.
He also reflects on how human trust and acceptance may matter as much as technical breakthroughs in determining when robots become part of daily life.
Please enjoy my conversation with Sergey Levine.
