Technology: an Angel or a Demon Technological advances have improved every aspect of our life, it plays a vital part in our modern life, but it can cut both ways. On the plus side, for example, cellphones can enable us contact with the other everywhere and every time. The planes save us a lot of time when we travel around the world. The desktop make shopping convenience for us to purchase online. In a word, technology has helped us lead a more comfortable life. But on the minus side, technology can be used to commit a variety of crimes. For instance, it can be controlled by some people who are able to hack into banks and transfer huge amounts of money to their accounts. What is worse, if technology used in war, the consequences would be unthinkable. Therefore, technology is both an angel and a demon.
