I'm still trying to come up with a test to prove that you are not killed and a duplicate takes your place on the other end who thinks it is you.
If they ever come up with teleportation, of course.
This reminds me of the time my house was robbed. Some thief took every stick of furniture, every book, all of the silverware . . in fact everything I physically owned and replaced it with identical belongings in identical condition. Of course I could see the diabolical thinking behind such an act. I could never go to the authorities with this theft. They simply wouldn’t believe me. So here I sit with all of this fraudulent belongings and nothing I can do about it.
