advent of large language models
maybe this was the multi-task representation we've been looking for all along?

Multi-task learning + grounding in language seems more likely to lead to positive transfer

Some limits of "language" as intermediate representation?
- loses spatial precision
- highly multimodal (lots of different ways to say the same thing)
- not as information rich as in-domain representations (e.g. images)

Perhaps this is where other representations can help us: e.g.,
