I think the main differences are internal state and feedback loops. The language model is stateless and immutable, whereas human brains are stateful and plastic. To mimic state within ChatGPT all the previous prompts and responses are fed together with the last one. But of course, that's not very efficient and quite limited. While it's certainly impressive right now, it's nowhere close to general intelligence. Once AI will be able to keep track of stage and update itself through feedback loops, then I'd say we'll be pretty close. Right now it's a language model that is extremely good at detecting patterns and applying them.
