The advent of dynamites was an innovation. Dynamites were considered the best means of mining until they proved to be the best tools for genocides. The emergence of streetcars was a tragedy. Streetcars were dismissed as life-threatening until they proved to be one of the most practical forms of transportation. Often inventions of the century are valued differently over time. The Internet is no exception. Unlike the times when the Internet was considered a product of superb creativity, today the situation is different. Some people point out several side effects of the Internet, arguing that the Internet has made people stupider. However, such negativity must be another tentative assessment towards the Internet over time. In my opinion, the Internet makes people even smarter for three reasons: human relationships, education and knowledge. To begin with, the Internet makes people smarter in terms of human relationships. The word “intelligence” can be defined as an ability to improve the current situation in a preferable way. In this context, the meaning of intelligence is not limited to an intellectual aspect, but also includes that of human relationships. In other words, the ability to improve one's relationships with others can be called intelligence. Therefore, the Internet, which allows people to advance their relationships consistently and transcending the boundaries of time and space, makes people smarter. For example, in a society where time equals money, people are absorbed in physically and financially productive tasks. As a result, interactions with others were pushed aside. However, the Internet allows people to stay in constant contact with others. Via Facebook or Twitter, in the middle of the document, the information is not limited to general facts and effects, but also covers the positions of other countries. Even if Koreans are unhappy with the FTA with the United States, they will also be able to find positive results of this agreement by reading the news or articles written by American scholars. In short, the Internet is a means of providing diverse and in-depth information. So people can broaden their views, which can be called smarter. In conclusion, I believe that the Internet makes people smarter given its role in connecting people, improving the quality of education, and broadening perspectives. Nothing can be perfect. Fears of likely negative outcomes cannot constitute a reasonable basis for opposing the Internet. With practical countermeasures, the Internet as a catalyst for improving people's intelligence is not difficult to imagine..
