No they didn't? I use these continuously and it's pretty obvious to me that they do not at the level of a human except in the most surface level ways. Human's as compared to an LLM remain a special category. We have not in fact cracked human level intelligence.
Even if we assume transformer models as intelligent (quite a big leap of faith), this just proved that humans are even more special: not only they are intelligent beings, but they can also create intelligent technology.
