Suppose your brain has ceased functioning, been recoverably preserved and scanned, and then revived and copied. The two resulting brains are indistinguishable in the sense that for all possible inputs, they give identical outputs. (Posit that this is a known fact about the processes that generated them in their current states.) What exactly is it that makes the revived brain you and the copied brain not-you?
Oops, you’re right. I have now revised it.
