I understand you're point that makes sense but i feel most people would use it even for if its debugging errors ect. Also gonna probs get harder and harder to tell whats ai and not. Or how much of it was Ai or not. Im sure there are people using it but say they are not.
You also imply that AI is recognised as a form of plagiarism. Which it is not. You can claim, that many view it as unethical, if you want. That would be true. But it is not recognised as a form of plagiarism.
