Suppose we can copy all the DNA structure, chromosomes, cellular information and other important parts that I couldn't name and replicate an exact copy of ourselves. Is that replica really ourselves? Or would it be someone else?
Are we a physical structure? We can create logic and teller machine but can we recreate consciousness? Where did that thing came from? If that's the manifestation of a physical phenomenon, like your computer browser, or your mp3 player, which is a manifestation of your computer hardware, we can easily replicate one, can't we? For software must exist together with hardware. Can our consciousness exist without our physical body? Can our consciousness be ever reproduced, like copying a song from the Internet?
Its only a matter of time before we create an artificial intelligence that is smarter than our own. And then whose to say that we won't just download the information from our own brain into one of those computers.
We already use robots and computers to do most of our work in space. What if we built a computer with the AI that is smarter than our own and sent it out into the far reaches of space, perhaps even into a black hole just to see what happens. What if that machine actually met another advanced civilization?
What if we sent that same robot with a case of human and animal DNA, with orders to, if it ever found a planet that was hospitable to humans, to clone the dna and create life.
What if we humans never do find another hospitable planet to live on, perhaps we find a suitable planet but theres no oxygen in the atmosphere. What if we modified our own bodys and replaced our lungs with something that was capable of breathing in whatever was in the atmosphere on that planet. What if that planet's gravity is twice that of earth, do we replace our muscles and bones with those that are stronger?
Where does it end?
Would not mankind still be living on in all those cases, even though not in its original form?
