Digital self-copy via AI/ChatGPT could be interviewed by later current self with big enough database. It occurred to me that with a large enough "language set" or database of various information, one could set up an AI/ChatGPT to query one's previous self, giving a whole new level of access to one's thoughts and memories, instantly. If one asks one's self, for example, "what was I thinking when I bought that car in 1982 insteady of keeping my old one?", ChatGPT would spit out a response based on records from that time showing one's line of reasoning or faulty thinking. Similarly, one could gain insight into why certain partners were chosen or what job choices were made.
