I'll never trust teleportation tech and transfer of consciousness to another body. There is always the question of, "is it still you you?"
Think of it this way, what if it was successful but you are also still there in your original location? Or, the consciousnesses that was supposedly transferred is also still existing in the original body?
The most logical conclusion is that the "you you" is the one in the original location or body. The person that showed up in the target location or the consciousness in the new body is not "you you".
In other words, you never really teleported or transferred consciousness!
I'd rather trust:
1. Folding space or quantum travel
2. Body regeneration or chromosome reprogramming
Because then, I know that it's still "me me".
This problem was perfectly demonstrated in the film #ThePrestige. When the "teleportation" machine did its thing, it did transfer the person to the other machine but there's a copy on the original machine.
Or, the original was left in the original machine and the one that appeared in the second machine was the copy.
So, who's "you you" in «The Prestige»? Who was original?
We will never know. Only the person who was duplicated can answer that question but of course both will answer "I'm the original!" Not because they don't want to die, rather, that's what their brain is telling them.
