Sir Arthur C. Clarke at his home in Sri Lanka. A visionary who predicted artificial intelligence and communications satellites that orbit the earth in fixed positions, Clarke characterizes the slow rebuilding process in the tsunami zone as "survival of the fittest." He enjoys listening to a media file of the wind of Titan, contemplates a future with "more people living off earth than on," who travel the "future homes of mankind" via space elevators. "Good wishes" he said this week, "to aspiring atronauts and cosmonauts" who will "go into space and look at the home planet."
