Sorry, I don't follow what you're disagreeing with. I was summarizing what Karpathy talks about in the vicinity of 1:31:00 - where he talks (I assume notionally) about a specific neuron lighting lighting up to indicate uncertainty, and how empirically this turns out probably to be the case. Edit: concretely, we can presume that OpenAI didn't specifically train ChatGPT to know that "Orson Kovacs" isn't a famous person, right? That's all I'm saying here - that they trained it how to say it doesn't know things, and it took care of the rest.
