This film was originally broadcast by the Australian Broadcasting Corporation (ABC) News as part of a report on predictions for the coming decades made by cutting-edge computing technology and leading thinkers of the time. The second segment features interviews with members of the Club of Rome, an elite think tank composed of government officials, academics and business leaders focused on the future of humanity. Their view is a bit sunnier, anticipating a world where global governments are forced to cooperate to solve complex problems, people widen their cultural horizons and work fewer hours, and limited consumption - not wealth - becomes a mark of prestige.
