As more and more people choose to keep their interpersonal relationship online instead of meeting people in person, the world has completely changed. People tend to make themselves look prefect on different social medias. People slowly refuse to accept their vulnerabilities. Making a little effort to build a perfect image online led many people to lose their self-awareness. They think that they are as beautiful as what they look online, and embrace all the thumbs-up from strangers. The camera of your smart phone never let you see your true self. All these changes prompt our society to get into some sort of virtual reality. The person on your social media apps is not yourself, it's just a digital substitute of yourself. As for young people, their idols also change from hero in reality to digital people online. Their idols never exist. The worst thing is that people from different generations likely become digital people. They refuse to meet their friends in person, because their best friend is their smart phone. So, who created smart phones? This is a scary question.
