My point of view is that the entire “you” concept needs to be constructed in the first place because it isn’t a self-evident, easily-defined thing. There are centuries of philosophy on this topic, none of it conclusive. Ergo: it’s kind of your call if you are even “you” when you wake up each morning, or just a fresh iteration with your memories that believes it’s “you.” Having hit my 50s I’m quite confident that the person in all my pictures from college is not “me” in any meaningful way.
