Teleportation mis-presented big time.
Teleportation basically tears you apart at the molecular level and puts you back together at your destination.
Sure, teleportation should be possible. Most science fiction comes true eventually. The railgun and weaponized lasers are reality. Fusion power plants are in the prototype phase.
Each teleport is the equal of destroying and creating a new organism with each jump. You should have no memories at all, since you were just born. Therefore, it's entirely possible your brain would be blank, and you would fall dead on arrival. There was a Star Trek Voyager episode of a similar nature titled Tuvix.
