It's a self-referential loop. Humans have difficulty understanding intelligence that does not resemble themselves, so the thing closest to human will get called AI.

It's the same difficulty as with animals being more likely recognized as intelligent the more humanlike they are. Dog? Easy. Dolphin? Okay. Crow? Maybe. Octopus? Hard.

Why would anyone self-sabotage by creating an intelligence so different from a human that humans have trouble recognizing that it's intelligent?
