A thought i n the mind transfer
Ive been thinking alot about this.
Lets suppose you can read out every neuron pattern in your brain. Then copy it to somewhere or someone else.
Copying would destroy the original.
This applies to teleportation too.
There is NO way it would ever be you being transfered. It would be exactly like you in every way. Much like in Freejacks ending as it should have ender if it was not for the twist. The digital and the version of the boss who was supposed to get Alex body. To everyone else it would look sucessfully. But the actual person having the transfer would in theory layout there, dying and watching another person with his entire personality stand in a new fresh body. But the actual him would never be transfered. It would only look so to everyone else.
To put it a bit more spiritual. Your "soul" would never be transfered. And by that, the very first time Captain Kirk teleported, he ceased to exist. From then on, it was his personality and everything he knows. His original self died before the first episode.
