They say we don't use language for thought, but language informs our strategies and choices, and collective experience is essential for progress. We only add small increments of insight from our own experiences to the pool, but the experience captured in language is greater than any one of us.
And more interestingly, LLMs trained on this data show amazing capabilities that go beyond mere reproduction. LLMs gain everything Einstein lost in this experiment, what is the language part and what is the pure insight part? Looks to me humans are like LLMs on feet, and with a full social complement surrounding them.
