With these neural networks [e.g., the type of AI ChatGPT uses], there’s no concise explanation. There’s no explanation in terms of things like checkers moves or strategy or what we think the other player is going to do. All we can really say is just there are a bunch of little numbers and sometimes they go up and sometimes they go down. And all of them together seem to do something involving language. We don’t have the concepts that map onto these neurons to really be able to say anything interesting about how they behave.
