I am perfectly serious when I suggest a world in which we can be in instant contact with each other wherever we may be, where we can contact our friends anywhere on earth, even if we don’t know their actual physical location. It will be possible in that age, perhaps only 50 years from now, for a man to conduct his business from Haiti or Bali just as well as he could from London
