I disagree. AI is good at pattern recognition, but still struggles to grasp causual relationships. These Made-up api calls are just a pattern in the large data set. Dont confuse it with creativity.
As to creativity, that's something I know too little about to define it, but it seems reasonable that it's even more "fuzzy" than intuition. On the opposite, causal relationships are closer to hard logic, which is what LLMs struggle with- as humans do, too.
