But's it's precisely this reference to "my meatbody" and "my computer body" or whatever that confuses me. When you upload, a new consciousness is created, right? You don't have two bodies, you just have a super-doppleganger. He can suffer while I don't, and vice versa. And he can die, and I'll go on living. And I can still die just as much as before, while the other goes on living. I don't understand what about this situation would make me okay with dying.
So I could understand it as valuable to someone for other reasons, but I don't understand its presentation as a life extension technology.
I understand what you are saying, and I think that most people would agree with your analysis (at least, once it is explained to them). But I also think that it is not entirely coherent. For example, imagine that we had the technology to replace neurons with nanocircuits. We inject you with nanobots and slowly, over the course of years, each of your brain cells are replaced with electronic equivalents. This happens so slowly that you do not even notice -- conscious is maintained unbroken. Then, one at a time, the circuits and feedback loops are optimized;...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
