You are everything there is that you can experience. The things you see, hear, etc, are really just sensory inputs produced by your own organs. Higher abstractions such as your thoughts, ideas, etc, are built upon these inputs that you produced. By changing your narratives, your physiology, etc, you can change how you feel about the world, or "the world", so to speak. You are everything there is to you. And then there is the I/O aspect to it. By interacting with these inputs and constructing models about "the world", you learn that you can receive future inputs that you want by outputting data (e.g. moving your hand to type these words, etc) based on the right simulations about "the world". You learn of your dependencies to abstractions such as "your parents", "friends", etc. It is in this way that you are not alone.
