As it turns out, when you heat up water, you get steam. And beginning around 1784, through the advent of the steam engine, steam was powering everything from agriculture to textile manufacturing (the age of mechanical production).
Society, which is used to be largely agrarian, which is a fancy way of saying that life used to be centered around farming. But with the steam power, those agrarian societies gave way to urbanization. The world began to rely on steam power and machine tools, while steamships and railroads revolutionized how people move from one place to another and the factory (in the city) emerged as the new center of community.
Ultimately, cities and industries grew more quickly than ever before, and economies grew with them.
With the invention of electricity things started to speed up with a number of inventions such electric lighting, radio, and telephones transformed the way people lived and communicated (the age of mass production and assembly lines).
People started to follow jobs, and we saw workers leaving their rural homes behind to move to urban areas and factory jobs.
This is the revolution which ushered in the modern world.
The third industrial revolution brought semiconductors, mainframe, computing, the Internet, brief the Digital Revolution. During this revolution, things which are used to be analog moved to digital technologies (Automated production).
Where are we now? At this moment, many of the technologies people dreamed of it in the 19th and 20th centuries have become a reality, the science fiction became science fact.
In this evolution, we got robots, flying cars, autonomous driving, genetic sequencing and editing, artificial intelligence, miniaturized sensors, 3d printing, to name just few, etc. And when we put some of these technologies together, the innovations are unexpected and surprising (exponential).
This revolution is different from the previous ones.
