Teleportation of Macroscopic objects will never happen.
Even if it did, it wouldn't be teleportation so much as transmission an an exact description and exact duplication at the desitnation. You would make a copy.
If you could identify the exact position, charge, spin and energy of every particle and force carrier in the region of space that contains you, could translate that (what would amount to trillions upon trillions of exabytes of information) and could recreate that same region of space using a source of particles at the destination, would it still have your "soul"?.. would it be a sentient person with a mind?
Interesting question, but I think personally.. no.. it would not be "you".
The 'Rat solution to the duplicate macro-organism problem: Just Euthanize the original.
Can someone save a copy of me during the teleporation process? Right?
For teleportation the machine makes a copy, sends it in some sort of digital package, and re-contructs on the other side. Can I keep that copy so that I can jump off a cliff and then will someone please use the copy to make a new me so I can do it again?
"Never" is a long time, even for Ents.
