I would imagine that teleporting is actually quite dangerous, in all it's (fictional) forms. Imagine it was magical and you just kinda popped into the spot you were thinking about. But what if there's something occupying that spot now? Would you just teleport into it? Or would it swap you and whatever was in that spot? What if there's still more of that object there? Would you suffocate in a newly built wall or get squished by moving machinery? You could always teleport only to places you can see, but I imagine that would be quite disorienting. Zap, your entire field of vision changed without you registering any movement. You'll proably get dissy and accidentally teleport somewhere dangerous. Or let's go with the Star Trek like beaming. Are there transcription errors that slowly build up? What if the exit node uses a different kind of encoding than the entry node? Teleportation seems awfully dangerous.
