It's unclear in what sense it is "anthropomorphizing" to say that systems that convey all outward manifestations of thinking are "thinking." We don't observe their internal state & can't easily discern it. AP suggests the same of animals, which, I believe, unequivocally "think".
No, "anthropomorphizing" is a technical problem, about how AI works, not something like woke language policing. We say it's wrong because it's "technically" wrong not "morally" wrong.
If you fail to set the brakes when parking on a hill, and your car then rolls down the hill, you don't claim that the car "decided to drive away on its own". Such anthropomorphizing distorts what really happened -- that you failed to set the brakes.
The same applies to AI. When you "anthropomorphize" the AI you fail at understanding what actually happened.
