In fairness the idea that a Mike can pick up my voice and transfer it by wire as electronic impulses and rebuilds exactly what I say in my accent half way across the world sounds like magic. And it has existed for years now
I'm not sure that's the best example. Radio technology and microphones have been around for well over a century now and its not that farfetched based on that fact to think that it exists. Think about it this way: What if a working flat panel TV suddenly appeared in front of someone from the 1700s? It gets turned out and the individual just wouldn't know what to do with it -- in absolute awe of it and the magic surrounding bringing moving images that look just as good as reality, they would be absolutely awed because they have no frame of reference. Or in a more apt example, if someone from today was beamed aboard a starship. Its something they've always known as science fiction. How would you react? Either thinking its totally cool, you're freaked out about it, or you remember conversations with your geek friends asking about how turning energy into matter and back into energy would basically mean that you've been killed and cloned. Then the person on the starship says they dealt with that problem. What's your reaction to that? "Magic!"
