I don't if I'm pleased that you understand, or infuriated by the fact that I've been saying the exact same thing all this time!

And then attempted to ask some questions to determine why you thought they would diverge when I had clearly stated they experience exactly the same thing (many times), to which I got:

No, I am claiming their location is relative to other walls (and objects) in the room. For instance, the left-hand wall is 10 feet from the right-hand wall, and so on.

Because that is what this entire debate is about, can you prove the walls are different? Can you even know the walls are different? You point to the left-hand wall and your copy does the same, you see your copy pointing to the right-hand wall and your copy sees the same.

I'm simply trying to find out where you think the copies will diverge. If they point to the left-hand wall and see their copy point right and think, "he's pointing to the wrong wall" there's still no divergence. This I think, you now understand.

So if we've established that they will not diverge in thought, deed, or experience, can they act as redundancy?
Even though you say you'd agree to being uploaded "atom by atom" (I'm not quite sure how this would work in the context of uploading) once you're on-line it's likely you'll be prone to the usual computer techniques of back-ups, redundancy and time-sharing.
