In 200 years, it is difficult to predict what the world will be like as technology and increased knowledge will continue to shape the future. It is possible that people will have longer lifespans and that diseases will be cured or prevented. Human creativity and technology might have created more efficient energy sources and the transportation of people, goods, and information may be instantaneous. It is also possible that new economic and political systems have arisen and that new challenges are present. It is likely that communication and collaboration between cultures will be more common and that humans will have left their footprint in space.
