Is it really that baffeling? Take ChatGPT, a model specifically fine tuned on dialog interactions to seem more human like. Of course people are going to anthropomorphise it. And the whole thing about it not being AI but an ML model, I think we can let that one go. It didn't stop the term cloud computing ("it's just someone else's server") and it won't stop the term AI from being used for this tech.
It's baffling because it's being done by people who would otherwise insist on technical correctness and rebut any argument otherwise with "well, how do humans think?"
