> How would you test whether some arbitrary thing is simulating the human brain? In my first comment, I didn't claim that it's simulating the entire human brain but aspects of it like language and memory. We can test such aspects by throwing text at the model and comparing it to responses of humans. A simulation doesn't need to have the same abstractions. What counts is solely the quality of the response. If the responses are sufficiently close to those of humans, I'd say it's simulating a human brain.
