Technology changes the way we work in many ways. One of the first industrial machines used water to replace some of the work done by animals. In 1781,Jame watt invented a steam engine that did the work of 10 horses. It seemed unlikely that these engines would change how people live and worked. However, within 100 years,, the work of some steam engines was equal to that of 10,000 horses. Because of this, fewer farmers were needed on the farms. Workers move to the city to work in the new factories. At first, life for the workers was difficult.
Then, they got together to form workers’unions and began to fight for better wages. Later, electricity changed people’s lives again, and then came automobiles. More recently, computers have changed our live once again.
The next big new technology will be robots. The best application for robots is in areas that are dangerous. Today, robots work side by side with people to provide military security. In the army, they fly over an enemy and send back information. Some have guns and can fight alongside soldiers. Another area where robots are useful is clearing up dangerous industrial waste. The waste can cause diseases, such as cancer. Robots will change our live just as steam engines did.
