There is no symmetry. The original existed when the clone did not exist.

Only if you deny the reality of consciousness being tied to a physical substrate.
replyIncorrect.
replyTo deny that is to assert that consciousness is non-physical, i.e. a soul exists; the case in which a soul exists, brain uploads don't get them and don't get to be moral subjects.
It's the exact opposite. The original is the original because it ran on the original hardware. The copy is created inferior because it did not. Intentionally creating inferior beings of equal moral weight is wrong.

replyBeing on non-original hardware doesn't make a being inferior.
>I'm pretty sure I could use that same logic to argue against organ transplants.
replyWhen the organ is question is the brain, that argument is correct.
