Earlier quoted context omitted.
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.
It is actually possible to rewind LLMs and get the same response, but it's not typically done both as an optimization and as a defense against distillation.
