After many years of research, scientists have invented the world's first teleporter! The device reads your atomic structure, destroys you, sends that information to another teleporter, and reassembles you at the other end. This means that you died, and an exact copy has been created. Or is it still you? Who are you? Did you die? Are you still you? Also read this. It's hilarious because it makes fun of all the nub scientists who aren't physicists.
I don't think teleportation would be invented before we have the technology to create connected wormholes. But if this sort of thing ever did happen, I'd stick to walking
I'd use that with the self-destruct feature disabled, then sue my clone for copyright infringement so they'd have to pay me back for the rest of their lives.
