They actually have successfully teleported something. A particle, I believe. Something to do with the weirdnesses of quantum physics, in the way we now already have quantum computing, whatever that is. (Is there any quantum computer in the world not being used to mine Bitcoin, whatever all that is?)
So we may eventually have teleportation. But to my mind — and here’s the sci-fi thought — long, long before we have the ability to teleport a human being (if we ever will, considering the possible merging of science and spirituality one day) we would be teleporting atoms of inorganic material to build stuff, i.e. using teleportation like a 3D printer. But if we can ever get to the stage where we can teleport food, that would make it fairly easy to solve world hunger. By then, all those centuries later, whatever computing is would be so advanced that if we could move food molecules around, we could easily feed anything on the planet with a stomach.
That thing. No real premise for anything. Just a sci-fi thought.
