Recently I have come to discover that there are so many great movies that I have been missing all these years. I am particularly referring to the Alien film franchise starring Sigourney Weaver as Ellen Ripley, an officer who is in an endless battle with an alien species in all the four installations of the movie. I can’t help wonder why I didn’t bother to watch this great movie so far. Today I finished watching the fourth installation and I must admit that I feel inspired by her character. I would certainly like being an officer like her in a spacecraft on a deep space mission. Anyway, the one thing especially in the fourth movie that caught me thinking is the resurrection part. Ripley was resurrected through cloning using the blood sample collected before she kills herself in Alien 3.
I am perfectly okay with cloning Ripley to resurrect her using her blood samples. But what puzzles me is that she possesses the memories of her past life once the process is complete. That simply doesn’t make sense. There was no way the memory could have gotten stored in her DNA. Obviously the memories weren’t stored in any retrieval unit either because there was no mention of that in the film. My problem is not whether she had her old memories or not. My problem is with the concept of consciousness. Let’s take cloning itself for example. If I clone myself completely and then transfer all my memories into this new person, he will lead his life thinking that he is me unless of course the final memories which contains information about the cloning is transferred as well. Even then there will be a confusion as to who is the “real me“.
So, unlike the villain’s point of view in the movie The 6th Day, we don’t get to live forever as our clones are the ones who look and feel exactly the same way as we do and also can possess our memories through transfer. But they are still not us. A similar problem exists with Quantum Teleportation. The information of me is first transferred to the destination. For that the quantum states of all the particles that in my body must first be retrieved and stored into the teleportation system. Then I should be destroyed at the source. The information transferred will then be used to recreate “me” at the destination just like in Star Trek. Again it is a problem because the person at the destination will be my copy and not me. If the process fails to destroy me then I will be here at the source and to make matters worse, there will be another person who looks exactly like me and having my memories created at a destination thousands or even millions of miles away.
I don’t know how can the people who say this is not a problem justify it. However, when I think about it, the person sitting and typing this blog post right now is really not “me” either. Since my birth, the atoms in my body has been replaced through life’s processes such as consuming food, expelling waste, taking bath and so on. It is entirely possible that none of the atoms that originally made up my body in 1984 exists in my body today. But I still have the feeling of self or the feeling of consciousness about myself. That is quite hard to explain. Why do I feel this “uniqueness” about myself? So much that creating a clone of myself will not assure me immortality. It only assures the existence of another person like me.
Most of us are afraid of death as it brings to an end all the beautiful experiences that life offers us. Being truly immortal thus would mean keeping alive all the cherished memories and experiences forever. With more advanced technologies, the time is not far before we can backup our own memories. But will there be a way to store and retrieve the feeling of “self“? If I transfer my awareness of self to a computer, will the “self” leave me to enter the computer or will I still have it? If I still have the feeling of self then what is it that got transferred to the computer? These are not easy questions to answer and I am not sure whether theology can answer them any better because of the problems I just described.
I have a lot of faith in science. I feel that some day science will understand what exactly it means to be self-aware and also find a way to transfer this consciousness of self into a machine or a clone without creating the paradoxical situation mentioned above. I wish such a breakthrough happens during my lifetime. When the human race leaves Earth and starts to colonize other planets and reach distant stars in the future, I would certainly like to have a piece of that action. I seriously don’t wish to be in a situation where my consciousness dies with me and I miss all the great things the future human race will achieve. I would want my consciousness of self with all its memories to live forever either in a being like me or as a sentient being if the technology of the future allows.
