Here is a question. Say I want to live forever and constantly move my brain from one body to another, so I never age. I also replace non functioning parts of my brain with new ones made with stem cells. Eventually after living for a long enough time my brain is no longer anything like the original except for its collective memories. Would that thing still be me? To take it a step further I create clones of myself and each of them has a small part of my originals brain. Would I still exist? Or I created a collective consciousness in which I am able to communicate to each of my clones and we are able to share our experiences in one big cloud. What does that even mean for me? Am I even the same person or something completely different?
These problems have been really bugging me and I am just trying to see if anyone has any answer.
