Why are so many industries replacing human workers with machines? For starters, robots are able to perform certain tasks faster and more efficiently than humans. Machines never get sick, don’t take time off, and don’t need to be paid. Often, it’s cheaper for businesses to use technology than to hire enough human workers to do the same jobs.
The National Institutes of Health, for example, is using several robotic systems to run lab tests. A single robot can run 3 million tests every week. A person would need to work eight hours a day, seven days a week, for 12 years to run that many tests.
Aside from their speed, robots can put themselves in dangerous situations so that people can remain out of harm’s way. Experts say that sophisticated robots will soon serve as first responders following disasters, like earthquakes, floods, and wildfires.
Robots might even be used in battle. Former U.S. Army General Robert Cone has predicted that robots could replace thousands of soldiers within the next few years, which could save many lives.
Another upside is that technology is creating new jobs that didn’t exist even a decade ago, like app developer and social media manager. Tech companies like Google, Apple, and Facebook employ millions of people. As long as robots are part of the workforce, there will also be a need for people to design, build, and maintain them.
In a less direct way, too, technology can improve the economy and spur job growth. By creating products more efficiently, for example, machines enable companies to lower their prices. When goods are more affordable, demand for them can increase, thereby requiring companies to hire more people to meet that demand.
