## Summary

Yann LeCun强调了大语言模型（LLMs）的实用性，但也指出它们缺乏对物理世界的理解，无法预见行动后果，这限制了其在构建机器人丰富未来中的作用。

## Key Takeaways

- LLMs是有用的，尤其是在添加了许多附加功能后。
- 未来的机器人需要能够理解物理世界并预见行动后果的AI。
- 仅依靠LLM不足以实现非反乌托邦式的未来社会。

1. I never said LLMs were not useful. They are, particularly with all the bells and whistles that are being added to them. I use them. 2. A robot-rich future can't be built with AIs that don't understand the physical world and don't anticipate the consequences of their actions. And LLMs really don't. 3. The future in the cartoon looks pretty dystopian TBH, but even a non-dystopian version will require world models and zero-shot planning abilities. 4. I rarely wear a suit and absolutely never wear a tie. 5. I would never ever place a coffee mug on top of a piece equipment. 6. I hope I'll look this young in 2032.
