I was wondering to myself about teleportation once, about how the information that travels through the internet is just a copy of the original, but an outside observer can't tell the difference either way. If humans learned how to teleport, there would always be a small suspicion that the people who come out through the other side would simply be copies of the original people and no one would ever be able to tell the difference... furthermore, that would mean that the original person (or their consciousnesses) was destroyed o_0
