Complexity scientist Melanie Mitchell highlighted her conversation with Rao about a Wall Street Journal column by Christopher Mims titled "AI's 'Thought' Process Can No Longer Be Trusted," which examines the questionable semantics of LLM reasoning tokens — whether chain-of-thought output actually reflects the model's internal reasoning.

Mitchell adds a pointed question of her own: could they ever be trusted? Her framing suggests the issue isn't declining trustworthiness but that the semantics of reasoning tokens were always suspect.
