As cool as teleportation is, i would never personally use it.
For all that i know, the moment i teleport for the first time there could be a malfunction and i could be terribly forgeted up.
Or what if the teleporter wipes my sentience, yes it can teleport the body to the other side of the world but of what use is that to me if i cannot live after that, even if i did have my sentience, is it really the original me, or the clone me made by the teleporter...
