I have always had this thought experiment that troubled me. If I could clone my body and my mind down to the exact molecules and atoms (which means there are two of my bodies that are exactly the same, with the same memory and mind), which of the current two bodies do my current consciousness go?
At first glance it may seem obvious that my consciousness would persist in my "original body". But from the perspective of the clone, he would have the exact same experiences and memories until the moment of cloning, where he is suddenly "teleported" into a "new" body in a new location. From his subjective mind, he would have the exact same experience up to the moment of cloning. So does the me that would continue to reside in the "old" body.
My current consciousness (before being cloned), then, would have no way to differentiate between these two destinations. Since the experience and memory of the two minds are exactly the same leading up to the point of cloning. Does that mean the chance of my consciousness being transferred into a new body vs. continue to reside in 'old' body is exactly the same?
