But like, you can't know what someone would have said in the future if they aren't there to say it. No amount of LLM improvements would be able to know the real internal thoughts and memories of someone. You could guess, sure, but you don't know with any certainty.

People change. Small things change people - seeing a car speed by might alter your opinion on some variety of things, but no LLM was there to capture that moment.

It will always be a guess. You can never know for sure what someone who is deceased would think about something in the future since they are simply not there.
