Tea, Earl Grey, hot.
Two words. Penthouse Holodeck.
They are, in effect, the same thing.
As far as I can see, whether it's Star Trek or Cal Tech, the only difference between 'Beam me up!' and 'Tea, Earl Grey, hot', is in the first place the original item is destroyed as it's copied, and the second, the item is copied from a pattern previously saved.
Lots of questions to be asked and settled if this is truly real. It's the the effect of preverbal perpetual motion machine, even if the physics works. If you can copy the atoms of an object, then you can have unlimited objects. Unlimited Oil, unlimited gold, unlimited food. The entire economic base falls flat on it's face as everything valuable becomes worth only as much as the energy needed to copy it. Star Trek indeed!
That's before you consider the actual questions of teleportation by making a copy on the other end. If you were to step in, and they fail to complete the transfer, there really could be two of you! What if some judge is having a snarky day and rules that your wife is now a widow because your original body was physically destroyed in the move? How could you ever be sure it was really 'you' that stepped out, and not a saved copy days later to be manipulated into some nefarious act or experiment?
Paranoia comes easy when the possibilities are real. ;)
As a kid, I always wondered what it was like to have been born with barely a working telephone available, and see atomic power and computers and the internet... Not any more.
Are you quoting Einstein?
