What makes you, you? Is it your physical representation, your memories, your choices, your relationships? In the physical world, identity is deep and layered. But online, all of that is stripped away. To a computer, you are not your story. You are a login. You are a password, a cookie, or a session. You are a code sent to your phone. That is the entire test of your existence in the digital realm. Which means if someone else holds those same fragments, the system will treat them as you.
