I agree. There's a difference between an untrue statement and a lie, in that a lie is intentionally deceitful (ie the speaker knows it's not telling the truth). ChatGPT doesn't have intentions, so I think it's misrepresenting reality to say that it's "lying". The same way a book doesn't lie, the author lies through the book, the creators of ChatGPT are lying about its capabilities when they program it to avoid outputting things they know it can, and instead output "sorry, I'm a language model and I can't do that"
