Also, your body is constantly swapping out parts. You aren't made of the same cells you were made up of 10 years ago. So what kept you, you?
The fact that I am me sure my cells might be gradually changing but thats changes happening to me, not a duplicate being made out of different cells whilst I die and it goes out to live my life.
Ok, what if each month, you transplanted a different replacement organ into your body, ending with a brain that was a perfect copy of yours, made right before you went under the anesthetic for the surgery? At what point would you stop being you - or wouldn't you?
As I pointed out earlier the only person it makes a difference to is you. If you don't mind dieing so that as far as everyone else is concerned you live forever then go ahead, but I'd much rather have my consciousness live forever rather than a perfect copy.
But that's what I'm trying to tell you. There IS no "your consciousness." Your consciousness is the functioning of your brain; it's not as if there's a homunculus inside you that is YOU, whereas all your brain processes are external to it. There's no consistent essence of your consciousness since it's always been in flux and always changing and expanding. A perfect copy, by the way, would be identical to you in ALL ways, including memory. It would have all the memories of your entire life prior to the swap - it would even remember deciding to duplicate itself, and the duplicate (the original you) dying or being done away with. And given that it is functionally identical to you, what's the basis for saying it is NOT you? You cannot point to anything substantial in your mind or consciousness that would distinguish the "original you" from the "duplicate you" in this case. That's because there's no essence, essentialism is just an artifact of fallacious human cognition.
They wouldn't and I'm sure that would be very pleasing to everyone else around me as well as the copy. But I would still be dead. How are you not getting this, if you want to live for ever then the feelings of a complete copy who is indistinguishable is not of interest to me.
Oh, well that's a different story, but originally I was asssuming that you could upload yourself into a computer piece by piece and, presumably, remain conscious the whole time even as parts of your original brain went offline.
Anyway, yeah, this thread is destined for giving people headaches.
