Would you use teleporter technology if it existed? Why or Why not?
You know those sci-fi teleporters like in Star Trek where you disappear from one location then instantaneously reappear in another location? Do you trust that they are safe to use?
I'd duplicate myself more than once, and at least once so I could fuck myself.
I'd tweak the transporter to adjust my body as I went through it. Best weight-loss, gym routine, plastic surgery, dick-enhancement pill ever, all in one.
I would be the reason such devices would be strictly regulated by people with ethics. "Is it murder if you kill your clone?" "Who cares, energize and last one stabbed wins!"
How would you deal with yourself after you fuck yourself?!
Do you want a really creepy twin with much less resources than you to walk around the world? Would you wanna kill that person? No one would notice surely.
Similar matter is dealt with in the book Dark Matter.
