The author suggests that it is no longer possible for a society to regard any living man or woman as a hero. I agree that facing the mass media nowadays, it is hard to make ourselves perfect in any field. However, it doesn't mean that there is impossible to be a hero in our society anymore.
What kind of people can be defined as heroes? It is actually hard to define. There are famous stars, successful business man and even an ordinary person can be a hero. Consider a scenario that a father who might be an unknown, earning a little wage, but working hard to support his family. It might not be a hero in most people's eyes, but it is if we asked his daughter or other family members. There are a thousand Hamlets in a thousand people's eyes. Some people might think Bill Gates is a hero because he made our computer system easier to use, but others might think Bill is just a business man comparing Steve Jobs who bring our computer a revolution that makes our computer not only functional but also artistic. It is just too hard to make a standard for heroes.
Do heroes have to be perfect? Almost no hero is perfect. Everyone has drawbacks, some people just don't expose their bad habits. KaiFu Lee, who was the leader of Google China and CEO of Microsoft Research China, wrote seven letters to the students, helping them to find their dreams, and giving them suggestions about how to attain it after graduated, which made hundreds and thousands students benefit from his idea is the hero for most colleges students who study computer related majors. However, Zhouzi Fang who found there is some exaggerations discredited him on the Internet, but who doesn't have any flaws, a little mistake won't make what he had done for the students to be futile.
However, there is are some people who are possible for a society to regard them as heroes. Steve Jobs who funded Apple that bought us evolution in computer area.
