Say we get to the point where we download our consciousness onto a computer. While we live, we are constantly uploading our new experiences into this machine with our 'consciousness' right up until the moment we die. Once we die, the consciousness gets downloaded into a robot/other person/machine/whatever. Would you consider yourself to still be alive once 'you' wake back up? Is this immortality? (This assumes a perfect download without corrupted data) I struggle with this because I am not sure we would be able to tell a difference. In that sense, are we still living? What happens if you download yourself before you die and you have 2 of 'you' hanging around? obviously you would start having different experiences and memories, but if you were the 'you' with the body and not the 'you' with the machine, would you be jealous? Would 'you' with the machine understand this and feel sorry for the other 'you', but be okay since they will be living on?
