A copy of me continuing on not knowing or caring that it's a copy of me is of little importance to me. That's not my point. My point is that I will not be continuing on. Sure, a copy that thinks it's me will, and to the world, that would be me. It would have my memories and make decisions based on those memories in a way that would be the same as I would. But that wouldn't be me, literally. My mind, my inner voice, my experience of reality through my mind's eye, would not exist. I wouldn't exist. A copy of who I was continuing on doesn't help me, literally.
