GPT doesn't sit there pondering consciousness and deciding, emotionally, that it thinks it's bullshit. It most certainly doesn't then decide, on its own volition, to go out into the web and comment this to others for the sake of debating them.
It doesn't sit there contemplating anything by its own volition unless its asked to. Regardless of what consciousness really is at its heart (I admit that we still don't fully know), it's a distinct self-motivated thing that we can see in our human selves and which is seen in no LLM except as a simulation produced by specific prompts.
