I appear to hold a lot of the same views as Usul, so I'll chime in here.

I could have even made you waffle back and forth by repeatedly telling you that I lied.

You could, but since I don't privilege the original or the copy, it wouldn't matter. You can swap the labels all day long and it still wouldn't affect the fact that the 'copy' and the 'original' are both still me. No matter how many times Pluto gains or loses its "planet" status, it's still the same ball of ice and rock.

I'll go one step further than the pattern theorists and say that I am both, even after our experiences diverge, as long as we don't diverge too far (where 'too far' is up to my/our personal preference.)
