Is it? Do you believe that there is something more than pure physical phenomenon that make you brain work? If not, then what if we find a way to get your brain back to the state it was 5 minutes ago? It is just a matter of arranging the state of matter. Don't you think you would still be conscious but back to a previous state?
If you rewind my brain I expect to give you a similar answer to the one I gave you before. Which isn’t the case for LLM. You can literally replay a positive answer, then get a negative response that isn’t consistent at all with the one it previously generated.
