Who knows?? It all depends on how people react…
I think if it ever comes true, it will be a lot like the Internet! It’s great, it let’s us connect with friends more (like teleportation would!) but it can also be misused and makes some bad things happen 🙁 So it depends on who uses it and how responsible we all are!
Teleportation shouldn’t mess with reality I don’t think, but then it’s just imaginary at the moment isn’t it! Another question is, is it still me that comes out at the other end of the teleport or is it just an exact copy of all the atoms that made me and the original me is destroyed 😮
