The future of travel involves getting their either physically or by electronic means of duplication. And as we perfect the whole art of holography, you will find that a lot of human contact, face-to-face, will be accomplished by telemedia, duplicating the person, much like portrayed in "Star Wars" when Princess Leia appears on his little, tiny holographic figure. And it's reality reduced and then recreated at destination, and it's very valid.
