I think cold fusion, and thorium nuclear reactors will replace the current energy systems. I believe that we will develop anti gravity technology as well. We will see advances in medical technology that will see most diseases being wiped out and most genetic disorders being able to be rectified.

Additionally, we will form a lunar colony and have the starting elements of a colony on Mars.

We will see 1 child policies instituted in countries that have exploding populations like China, India, etc. In countries like Canada and the US that are actually seeing a decline on populations, it's not imperative as we're already heading in the direction of lower populations.

I also believe that we're just starting a economic depression that will last for the next 15 to 30 years and will result in some wars (civil and otherwise). The out put of that will be an economic boom as countries will try new ideas to stimulate the economy.
