LLM planning on robots! Open research problem, but here's one way to do it

Limits of language as information bottleneck?
- Loses spatial precision
- Highly (distributional) multimodal
- Not as information-rich as e.g. images
- Only for high level? what about control?

Machine learning is a box
... but robotics is a line

We have some reason to believe that
"the structure of language is the structure of generalization"
To understand language is to understand generalization
