Hi John, <...at the instant the air molecule hit you, your conscious experience will not have changed nor would that of anybody else.>
Your conscious experience doesn't change like it would change if you are hit by a brick, but the quantum state of your body changes (it is now entangled with the molecule). And this is why I don't think a perfect copy of a quantum state is needed for technological resurrection. <...so far at least the unmodified Schrodinger Equation has passed all tests with flying colors.> I would be very surprised if this remains the case for long. The history of science shows that *all* theories are eventually upgraded. We are babies on the cosmic scene, I think we still have a lot to learn. <...all you'd need is a glance into the night sky.> But perhaps they are subtler than that. Note that we observe wild animals with cameras hidden inside decoys that look & smell like one of them, and I've seen videos that suggest the animals think a decoy is one of them. Sure our super aliens are at least that smart.
