What do you think about immortality? Will people find immortality in the future?
Is it possible to transfer a digital copy of the brain to a computer environment?
Immortality in the sense of a digital copy is not true immortality. It is more along the lines of cloning. For instance, think of an organic human as a vinyl record and the digital copy as an mp3. For the most part you can say there is no distinguishing differences yet, the mp3 does not log all the dings, scratches and every other error present in the original. Just as when you copy any file on a computer it is not the original file, but a copy.
If your goal is to continue yourself from the state you were at when you died, then yes, that will suffice. The problem is, it isn't you. You still died. So you feel nothing. Your copy is what will experience the world after you die. Just as when you make a clone of say a dog, you know it is not your actual dog, but a clone of it. There is no difference from a dog and a person when you are copying its data. Both had an original and both have a copy.
The main problem is how we are created. Humans as they are now will never be immortal. But, if you follow the beliefs of tranhumanism, eventually humanity and technology will meld together until there is a point where there is no distinguishing difference between the two. Those of us born before that time will be doomed to die. After that phase though, humans will be created in a digital environment, so technically they would live forever as they do not have to deal with organic flaws. They would also not be classified as Homo Sapiens, or from the viewpoint of some, not human at all.
Also, I've always thought that if reincarnation is real then there is no reason to find immortality. You technically already are. You just don't stay in the same state forever. Which sounds more fun than watching the world pass by as the same person or thing.
I guess one of the first questions would be what your definitely of immortality. On Wikipedia, I found this, "Physical immortality is a state of life that allows a person to avoid death and maintain conscious thought." If you could actually upload your mind and have it function in some sort of computer, maybe the trick is just the transition. If you upload it and your copy starts "living" and thinking it's own thoughts separate to you, then you would die and the copy would live on. It would be distinctly different. If you died, then somebody turn on the save copy of you, you'd be dead and the train of conscious thoughts would be interrupted. Your copy would just go back to the time when it was uploaded. If you you could get it just right, so that your brain is uploaded while you were dying, you could get the effect of a continued train of thought. The body would die, but the mind would just move into the computer and keep working.
