So, am I me, or am I... a clone

"This is an existential question you will have to ask and answer yourself. What makes us ‘us’? The question is good, but I do not have an answer for you. What I can tell you is that you are very much you. Your memories are as real as anyone else's."

"You cannot be anything else than yourself. A clone? Perhaps. But a traditional clone doesn't carry the memories of his parent, while you do. You are an exact copy, indistinguishable."

• Is there another copy of me somewhere else?
