Have computers helped or hurt our lives?

Generally speaking, every invention has advantages and disadvantages. And whether users get good out of it depends on users themselves. This is also true for computers too. Computers are now prevalent around the world. Almost everyone has a chance to use computers. I think computers have brought about so much advantages than disadvantages that hurt our lives that it has helped us in total. There are 3 reasons that will lead you to this conclusion.

First, the use of the Internet has changed everything including society, economies, and communication dramatically. Take communication for example, we are now connected each other via email and social media that enables us to be constantly connected. If you want to tell something, you just have tell the computer to do so. The use of the Internet has trumped geography.This is definitely the example of computers helping us.

Secondly, computers help us to do calculation. Computers are good at doing simple and repetitive computation and memorizing exact numbers which are both human being are not good at. Take space development for example, the calculation of space shuttle launching, the speed of orbit, and other physics by computers have helped us explore the mystery of space. Without computers, with only human brain, we couldn't have done this exciting things.

Finally, computers shows virtually created new world. Computers are also good at simulating, such as the movement of consumers, the change of environment, and the scenery of old world. Take films for example, a lot of films now depend on computer graphics that enables to happen something virtually without actually make that happen. And 3D effect is now becoming prevalent. This whole experiments that we wouldn't have experienced without computers have definitely brought us a excitement and curiosity.

In conclusion, of course there are some side-effects that hurt our lives using computers, however, there are a lot more benefits using them. Because we are now connected over geographical distance, we can calculate faster and solve difficult problems, and we now can see the virtual new world.
