There is a loud slogan in the book: “People over the age of 25 are not credible!” However, the author of this book is over 25 years old. Whoever wants to save the world is so easy and so cool, let’s try it.

Since the author always preached the basic knowledge of encryption, chip positioning, and gesture recognition on the whole page, I just thought that this was a safety technical textbook disguised as a novel. After reading two or three chapters, I found out that there is indeed a story in it. If I look at a few chapters, I will feel that the safety technical textbook is better. There is no reason for it, and the setting is too unreasonable.

A big problem (or big advantage) of sci-fi in the near future is that it is easy for readers to compare reality with fiction and judge whether the virtual scene of the novel makes sense. For example, “Little Brother”, which only discusses existing technology applications, the comparison is readily available. At the beginning of the story, the United States is already a country that widely uses public safety monitoring technology. Then the San Francisco Bay Bridge collapsed with a terrorist attack, killing thousands of people. Based on this, the Department of Homeland Security continued to upgrade San Francisco’s surveillance and security, began illegal arrest and abuse of unrelated citizens, and caused the underground group of middle school students led by the protagonist to fight back by hacking, and was eventually defeated by crime exposure. This book was written in 2007, after the 9/11 era, so it is not necessarily appropriate to take the 911 that does not exist in the Department of Homeland Security. But in 2013, we can have a more appropriate analogy, that is the Boston Marathon explosion. Of course, the Boston explosion did not kill people. More importantly, the suspects were quickly identified through surveillance videos and later arrested. There was no continuous security alert and monitoring upgrades. So which scene is more realistic?
