As the world is developing rapidly, people rely more and more on science and technology. When they define the concept of science and technology, “most people today think of silicon chips, iPods, high-definition TVs, and visual cell phones” (Wilson 320). Among those high-tech inventions, cars and cell phones are two scientific inventions that mostly affect people’s lives. For example, they can get to the destination faster or simply make a phone call to talk instead of taking time to write a letter. However, all of these effects do not stop there. As people can observe, they no longer work manually or by hand because everything have become computerized. Therefore, it is not unreasonable to believe that “in the future, computing is not computers any more; it is about living,” according to Nicholas Negroponte (27). In fact, the invention of computers has had both positive and negative effects on people’s development, such as, in humans’ social lives, in their jobs, and in human entertainment.
First of all, humans’ social lives rely on computer invention because of its helpfulness. With the aid of technology, using computers with internet access is not an unusual way to communicate anymore. Since computers were invented, communication has become easier and quicker because “computers will join together to communicate with us and for us” (qtd.in Leone 13). For example, international students, who do not live with their family, can keep in contact with their parents via webcam. They can not only talk but also see each other’s face. Talking via webcam like that helps those international students feel like they are living far away from home. Maintaining better communications means maintaining a better relationship, so people might say that “computers can foster human contact” (Swerdlow 17). When people are bored or disappointed, they usually log in to chat room or facebook where they can meet many different and interesting people. For example, my friend’s brother immigrated to the U.S. ten years ago and left his girlfriend in Vietnam. The only thing that helped them keep in contact was the computers. They just kept chatting via webcam about how they lived without the other. Even though they did not live together, talking via webcam helped them maintain their relationship. Three years ago, they decided to get married. There are not many people reaching this destination, but computers provide people one way to keep their distant relationship.
However, using online chatting to communicate has its own side effect which badly affects people’s privacy. Although computers have made communication easier, quicker, and more convenient, it has also brought the privacy concerning. For example, every time people visit a dating or chatting site, all of the activities that they make will be saved and “can be converted into permanent records that, when combined with innumerable other such records, can form a detailed profile of who we are” (qtd.in Wagner 59). It is scary to see our profiles online, meaning that people’s privacy is known as public information which they never expect to see. In addition, most people use a credit card to shop online, and every time they use it, that credit card can be matched to specific titles and be stolen easily. Using credit card to buy something online is so convenient; however, it is not safe because some online hackers can steal people’s account number and start using it illegally. In fact, using computer to access the Internet has impacted people’s privacy.
Secondly, computers play a big role in people’s jobs because computers help people perform work faster and more correctly. Long time ago when computers were not invented, hundreds of people collaborated to trade stocks by using blackboards, chalk, and phones, and with much calculation, stock trading now is so much easier and quicker. It means people just simply turn on their computers, and all the information about stocks...
