A research paper argues that the most valuable capabilities of large language models are precisely those that cannot be captured by human-readable rules. The thesis is supported by proof showing that if LLM capabilities could be fully rule-encoded, they would be equivalent to expert systems, which have been proven historically weaker than LLMs.
