You know sometimes we're reading a story/watching a movie or series and then we see something that makes us go "That would be cool if it was real". But there are some things that, after giving some thought you conclude that there's no way you'd ever use in real life.
Let me give an example... Star Trek teleportation. It's cool, isn't it? You just disappear from point A and reappear in point B in no time. Well except for the fact it's not you, it's a copy. The original "you" was disintegrated by the machine that instantly created an exact copy somewhere else. Even the series acknowledges this in that episode where Commander Riker's teleportation flow is deflected in a planet's atmosphere and in the end there are two Rikers, one aboard the Enterprise and another one on the planet's surface. Seriously I'm not in such a hurry to get anywhere to accept being murdered and duplicated. I'll go by shuttle if nobody has any problem with that
