How is it any different at all from sleeping and waking up? How do you determine, each morning, that you're still you, for whatever value of that line you choose? Even more starkly: ever had surgery? Ever taken benzos? Or been black out drunk? I could give you an amnesic med, like midazolam (often used in surgery) then tell you that you were absolutely certain to die. And I'd be right (again for whatever flimsy values we're using here). The version of you that is hearing me tell you these things will disappear from earth. You'll wake up in the morning, none the wiser. Edit: Only scary part is staying conscious after the cutover. Greg Egan gets into some of this with excellent short stories in Axiomatic (The Jewel) and Luminous (Transition Dreams). But that's still not really much worse than benzos.
