I believe computer screens can make people happier, smarter, and better able to cope with the copious problems of tomorrow. But only if we do right, right now.
WHY?
The computer's capability for branching among events, controlling exterior devices, controlling outside events, and mediating in all other events, makes possible a new era of media.
Until now, the mechanical properties of external objects determined what they were to us and how we used them. But henceforth this is arbitrary.
The recognition of that arbitrariness, and re-consideration among broader and more general alternatives, awaits us. All the previous units and mechanisms of learning, scholarship, arts, transaction and confirmation, and even self-reminder, were based in various ways upon physical objects - the properties of paper, carbon paper, files, books and bookshelves. To read from paper you must move the physical object in front of you. Its contents cannot be made to slide, fold, shrink, become transparent, or get larger.
But all this Is now changing, and suddenly. The computer display screen does all these things if desired, to the same markings we have previously handled on paper. The computer display screen is going to become universal very fast; this is guaranteed by the suddenly rising cost of paper. And we will use them for everything.
[...]
Our screen displays will be alive with animation in their separate segments of activity, and will respond to our actions as if alive physically too.
