I would argue that’s not quite true. The brain is possible to understand at least functionally. If we look at LLMs as the language faculty, and that we’re brute forcing the LLM’s world models via language, but that we haven’t yet created the prefrontal cortex and consciousness, then every LLM behavior is obvious and predictable. The impediment to completing that circuit is that it dramatically increases costs.
