　　Intelligent machines such as robots are increasingly being used. They cando many things that used to be done by human. Discuss the benefits anddangers.

　　For centuries, people have fantasized that someday machines could haveintelligence like mankind and work as faithful servants. Today this dream hascome true in many fields thanks to rapid development in artificial intelligenceresearch. Wonderful as this seems, machines have problems.

　　To begin with, people lose jobs when machines take their places, especiallyin the mass production industry such as automobile business. In factories of thefamous car company Ford, almost every step of car making is done by giant robotsthat work faster with higher reliability and precision than human labor. Becauseof the adoption of robots, thousands of workers are put out of their old jobsand forced to make changes in their work. Even such changes create jobopportunities because robots need people to take care of and operate, the numberof new jobs is much smaller than that of lost, thus causing huge pressure on thelabor market and government.

　　People become less smart because of the wide use of machines in their life.Nowadays people need to use their brain less than they did in the past.Everything is programmed and the only thing we need to do is to push a button orthrow on a switch. This has given us great convenience but made us lazier andless smart. Everyone has the awkward moment troubling with the spelling of asimple word when writing with a pen. But with a computer, it will automaticallyproofread the spelling and grammar of your writing. So people become lessconcerned with learning things right. This is not a progress but a regress ofour intelligence and culture.

　　But machines have many benefits that nobody can deny such as great workefficiency and low cost of mass production. The workload that could take monthsto finish by manual labor could be done flawlessly by robots in minutes. We havemore purchasing power to enjoy a wider variety of goods and services because ofthe reduction of production costs with factories using machines. Other benefitsinclude that machines could do dangerous jobs for people in high risk businesseslike mining and construction.

　　To conclude, machines have many merits that make our life easier and moreconvenient, but they have caused many problems such as undercutting our jobopportunities and overdependence on machines.
