Unless supernatural properties of the soul exist, I don't see how the other you will be anything other than you yourself.
There's the point where religion and philosophy enter the room. IF there is a soul, IF there is a god, then your consciousness will survive the process and transfer from A to B. I don't think god would allow humans to kill themselves and copy their souls at the same time. That would be pretty inflationary.
Okay ... how about this: Your little boy or girl are trapped in a high-rise apartment building that is on fire and about to collapse. There is no way to rescue them. But there is a duplicating transporter available. It kills the subject relatively painlessly, but creates an exact copy that will remember everything you've taught her and she'll even call you "daddy". Do you beam her up and "rescue" her?
The rhetorical answer to that question is of course, yes. However, such a device would also theortically be able to de-age people using their DNA and create a younger clone And end result of that is immortality for those to have access to it.
Yes, I would make a copy of my kids if they were about to die and the technology existed. Anyway, why does destroying the original make this concept difficult for some? If you did it without destroying the original, then you could have a conversation with your copy and know that if you died at that very moment you would no longer be conscious even though your copy is standing right next to you.
No need to be creepy; a transporter can be loads of fun. I recently built one for my grandkids to play with and have instructions for building your own transporter HERE. Gary
