We'll never, I repeat never, see Star Trek-style transporters because information will always be cheaper to transmit than it is to transport matter. The end point of Star Trek-style transporters requires the reversal of Einstein's famous equation, converting energy back into matter. On the other hand, it is far, far more efficient simply to beam the information that could reproduce (clone) a person out of matter at the receiving station. This is akin to emailing the blueprint for, say, making an iPhone, rather than shipping it to the recipient. At a great enough distance, it would cheaper to clone a person from his or her genetic information using a molecular assembler (a souped-up 3D printer). The clone can then be programmed using the consciousness of the original (mind uploading). Far-fetched, yes. But vastly more energy efficient than effecting a reverse nuclear explosion.
