This is not a stupid topic! Don't you find enlightenment from educated predictions? Is it not a noble scientific passtime to guess at what cannot be proven?
Here's some of my guesses:
Space Age(you forgot this one!): In the search for new ways to acquire resources and take advantage of satellite technology private markets begin to capitalize on space. The idea of a space elevator does not sound so bad if you have governments waiting in line for multi million dollar rides. Nations revisit the idea of the 'Star Wars' missile defense system as a measure against smaller nations finally being able to construct nuclear ICBMs. 'Rods from god' satellites can hit a target within minutes and with no risk to the attacking nation. The field of war expands, as it did in world war 1: land, sea, air and... space?
Information Age continues: Computing power becomes faster and more portable, making populations able to organize revolutions with a few simple touches on a keypad. Knowledge as property of the elite fades as academic content becomes freely available to anyone who wants to study it.
Robotic Age: Attack Drones, automation of factories, Potential effects on the job market and the gdp as a whole. One man can do what used to take 50. What will this mean for the disparity of wealth?
Biological Age: Sweeping advancements in medicine and the understanding of the human genome. Life expectancy goes up, nutrition and exercise are redefined, sickness becomes easier to cure, and the question of genetic engineering of animals and plant life is brought back into the political arena by sheer practicality. Imagine an edible staple food plant that can grow in unfarmable conditions (desert? Tundra?), feeding millions who have nowhere else to go.
The Fusion Age: The sun's secret for creating energy has been unlocked and is practiced on earth. Fusion Power plants are the first to appear, followed by a massive push for more electric cars and high speed rail. Electric bills sharply fall and nations struggle to restructure their economies around this new form of power.
The Banker's Reign: Those bastards tricked us with an overcomplicated system of money and they end up taking over our economy. They plant computer chips in our mind and make us all into slaves, building pyramids in their image. Resources deplete themselves and whole populations stave due to mismanagement. This is the second dark age, but we shall overcome...
Look, most of what I say could turn out to be untrue, but I think it's natural to predict where technology will go.
