My faith in the future rests squarely on the belief that man, if he doesn’t first destroy himself, will find new answers in the universe, new technologies, new disciplines, which will contribute to a vastly different and better world in the twenty-first century. Recalling what has happened in my short lifetime in the fields of communication and transportation and the life sciences, I marvel at the pessimists who tell us that we have reached the end of our productive capacity, who project a future of primarily dividing up what we now have and making do with less. To my mind the single essential element on which all discoveries will be dependent is human freedom.
