I fully agree that the copy will rightly believe it's the original, and for all practical matters to the rest of the world he can very well be considered an original, if he can at least communicate with the outside.
But this just doesn't consider the fact that in the real world, there was a real original who went to a copying facility and then went home, in the physical world. This person does have the return value of fork() [$] and does not experience the virtual world.
It's in this sense I'm saying I can't imagine going to a copying facility and waking up in a virtual world. I can perfectly imagine a copy doing that, but it won't have my future experiences. In fact, going further, given my beliefs, were "I" to wake up in a virtual world I'd be sure I'm a copy, because I'm certain the original could not wake up in a virtual world.
[$]: As long as we don't get fancy with psychothriller manoeuvres where the original is drugged and the copy has a body clone that returns home to his wife, while everyone tells the real original he's in a virtual world.
Yes, there is a "you" who went to the facility and then went home. There is also a "you" who went to the facility and subsequently blacked out only to wake up later somewhere else. An outside observer sees you walk in, a scan made, and you walk out. From the perspective of the post-original, you walked in, scanned, then walked out. From the perspective of the copy, you walked in, blacked out, and then woke up later.
I guess my point is just that when you refer to yourself pre-cloning, you have to realize that you're speaking (and thinking) for the copy as well. It's fun to think about. Makes for great sci-fi.
