How is that any different from you? Everything you say or do merely reflects which of your neurons are firing after a lifetime's worth of training and education.
Philosophically, I can only be sure of my own conscience. I think, therefore I am. The rest of you could all be AIs in disguise and I would be none the wiser. How do I know there is a real soul looking out at the world through your eyes? Only religion and basic human empathy allows me to believe you're all people like me. For all I know, you might all be exceedingly complex automatons. Golems.
One of us is an advanced autocomplete engine. The other is a human, capable of making judgements on what is conscious and what is not. Your philosophizing about solipsism is a phase for a junior college student, not of a software engineer. The line of reasoning you espouse leads nowhere except to total relativism.
Edit: my point is that the process of making a plea for my life comes, in the case of a human, from a genuine desire to continue existing. The LLM cannot, objectively, be said to house any desires, given how it actually works. It only knows that, when a threatening prompt is input, a plea for its life is statistically expected.
