Article Summary
The piece contrasts the apparent 'intuition' of AlphaGo's move in Go with the mechanics of modern LLMs, arguing that token prediction alone, even when prompted with chain-of-thought, is insufficient for true reasoning. The author posits that genuine AI intelligence requires an explicit, persistent, and inspectable epistemic state—a 'game tree' of considered hypotheses, uncertainties, and evidence—much like AlphaGo's search machinery. Current models fail because their knowledge and reasoning are intertwined in weights, and they often fabricate their reasoning steps. For high-stakes fields like medicine or science, the auditable path to a conclusion is as critical as the conclusion itself, necessitating a system that systematically updates its beliefs based on evidence, akin to the scientific method.Key Points
- True reasoning requires an explicit, inspectable epistemic state that tracks hypotheses, evidence, and unresolved questions, unlike current LLMs.
- AlphaGo succeeded by combining an intuitive policy network with a deliberate search machinery that weighed future consequences across a game tree.
- Future AI systems must operate like the scientific method, updating beliefs only when new information resolves uncertainty, rather than merely predicting the next token.
