What picture do you have of the future? Will life in the future be better, worse or the same as now? Will this hot, flat, and crowded world be "standing room only"? People hope that by the year 2100, many of our current problems will have being solved.
Clean water will be one of the most valuable resources. Demand for water will have been increased ten times. In fact, there could be a serious shortage. Will water be more valuable than oil? Will we have found a way to preserve our most precious resource by 2100?
Energy will come from a variety of sources: wind, air, solar, hydrogen fuel, and nuclear fusion. Cars will have stopping using gasoline and will be using far more efficient means of getting around. Public transit is expected to play a larger part in our daily lives.
The boundaries between entertainment and education will disappear. Edutainment will have took over as the preferred system of learning. Parents stories of having carried backpacks with 60 pounds of books will be a source of amusement for children. Learning will be "on demand" and focused to specific needs in the world job market.
Air travel will be safer and faster. Computers will operate aircraft with sensors, which will make them incapable of having collisions with other aircraft or phenomena of nature. Problems that grounded the Concordes (SST) will have being resolved by engineers, and passenger aircraft will travel at a speed of Mach 0.1.
Robots will continue to replace people in manufacturing; however, personal services will be in high demand. However, by 2100, companies have replaced phone trees with human operators. Local items, such as food, clothing, and furniture, with an "artisanal" touch will again be preferred over more polished, less expensive items produced by robots.
What experts cannot predict is whether we will be kinder, more caring people. Will we have understood that violence and war only cause pain and despair? Will we be able to share earth's resources? Will we have stopped looking at our differences and start seeing our common goals?
