Do you believe that each run of a ChatGPT prompt has a conscious experience of its existence, much like you (presumably) do?
If you don't believe that, then you face the challenge of describing what the difference is. It's difficult to do in ordinary language.
That's what Nagel is attempting to do. Unless you're an eliminativist who believes that conscious experience is an "illusion" (experienced by what?), then you're just quibbling about wording, and I suspect you'll have a difficult time coming up with better wording yourself.
