At first, I want to say hi to everyone, i'm new and not american/english, please bear with me :3 @Godot, then I want to react about your message : if we are talking about quantic teleportation I do concur (due to intrication, sorry if it is not the full term or mistaking), the "you" the other side from an ethical point of view can be considered as a copy and not the "actual you". I think star trek picture very well what's happening during a quantic teleportation, as said by nearly everyone, your body's atoms configuration would be saved by a quantic supercomputer, sent to coordinate X,Y,Z at S speed then reconstructed weither by automated mean from the home computer (requiring to beam the data where you want to go I guess) Weither by a terminal at your destination (safe to think this kind of technology could allow you to copy and store yourself in a quantic/numerical state and be restored in case of fatal and unwanted/unfortunate death, limb severed, uncurable disease... Thus begining the age of the cyber human) But this technic implies a big flaw, does the "you" you've stored is really you, or not just a copy thinking it's you, when the "actual you" is dead, because of the demolecularization needed to store these very data and send it elsewhere faster than light (this is getting complicated and steam already blow from my ears) the Stargate from SG-1 would be the wormhole way of teleportation, a hole connecting two points in the universe by folding it, then it's safe to think you are not demolecularized and would just "pop" the other side (considering you put through your arm only, while your body stay in new york, your arm appear the other side from the event of horizon, if you pull it back, your arms dissapear from paris and is still your arms when fully in new york. but a lot of flaws can be foreseen, as the strain caused by the wormhole to the body, the energy needed to open both side of this wormhole with enough input to keep it open a minute or two, and does wormhole really not demolecularize yourself ? Just to give a few. In both case, it would be strictly regulated, at least for a few decades or a century, until peoples get accustomed, because of the need of heavy installations at first and for reasons already mentionned, I think that once we become a truly space faring species teleportations regulation would ease a bit, if not completly dissapear as privates at first and then commoners would get access to their own teleporter gradually like the cars was at first reserved to the elites when it really came out first, and then begun to become a part of everyone everyday life, so is the informatic. I may be wrong, if that's the case i'll be glad to have a proper explanation, i'm not confident about my knowledge in this topic =)
