Yep. My take as well. You kill the person and create a copy. The problem goes even deeper. Human consciousness is something nobody can explain or grasp. In fact, if you didn’t have one you could not be convinced through any scientific test that it even exists. Where would that consciousness go when you were vaporized?
And if it doesn’t go to the “copy” would the copy be “alive” or just so much meat - a corpse?
The transference of consciousness could create even more problems if it became possible. Think of the possibilities of the perfect spy.
Now I’m missing the show Quantum Leap.
