Regardless of how outlandish this seems, this idea and the similar idea of uploading yourself into an exact digital copy to live forever don't seem too appealing to me, for the obvious reason that it's a copy of you, you (the original) would still exist, and die, so what's the benefit to you?

I don't think I'd like knowing that that there was an exact copy of me living on while I (the original) dies. And it seems incredibly egotistical that you would think this is a net good for anybody, that it's worth having a clone of yourself (no matter how exact) living on, and taking up resources etc.
