I think the big question is what is the soul, or are we more than the sum of our parts. Some speculate that our bodies are merely an antenna which is tuned in to a specific frequency. If the body is nothing more than a biological vessel or an avatar, then the secret to immortality is to create another one and somehow tune it to pick up the signal. If possible, the soul (or player) may experience bilocation. On the other hand, if the soul is simply the sum of our total experience on earth + the animating spark of life, we might be able to copy it, but that'd be far less impressive because a copy is only a copy. If we can only make a copy of ourselves and bilocation does not occur, it's quite a bit less special, making us highly replaceable. Some think the spark of life; consciousness, or the observer if you will--is a dismembered part of God experiencing itself subjectively through all life forms. When we die, God gains a lifetime of experiential knowledge, and we remember who and what we really are. Even if this is not true, one day, given enough time, we will make it so. Fractals in fractals, ever play a video game inside of a video game? Is that air that you're breathing?
