You're using the fact that the human brain has greater capability than ChatGPT as an argument that it's doing something qualitatively different.

This isn't enough of an argument. ChatGPT has greater capability than the smaller language models that preceded it, it can do tasks that they couldn't do, but it is not qualitatively different, it's differently mainly in the amount of information that has been encoded into it.

It is extremely probable that the next generation of large language models will be able to do things that ChatGPT struggles with. Perhaps those new capabilities will overlap much more with the human brains capabilities than we expect.
