“Who said computer science was difficult?”

I am so grateful that so many young readers have loved this book since its first edition was published in 2018.
Sometimes, we even receive contact from students who say, “Thanks to you, I started dreaming of becoming a scientist.”
Those were the days when I thought it was the greatest honor I could have had as an author.

To repay the love of many, and to further supplement the changes that have occurred in the five years since the book was published in our rapidly changing modern society, I have compiled the content that needs to be revised and added.
That's why we're introducing a newly revised edition of "What Teenagers Need to Know About Artificial Intelligence and the Future of the Fourth Industrial Revolution."


From the author's note

Technology has become stronger and faster!
Now, understanding AI has become a prerequisite for talent!
In the future era with generative AI such as ChatGPT and Midjourney,
How should young people make their own place?

This book, "Artificial Intelligence and the Future of the Fourth Industrial Revolution: What Teenagers Need to Know," which met readers at the dawn of the Fourth Industrial Revolution, has been loved by many readers, reaching 35 editions and remaining an online bestseller for 33 consecutive weeks since its publication.
More than five years have passed since this book was first published, and teenagers have praised it as "a systematic digital science humanities book that can be read like a storybook," explaining the vague reality of the Fourth Industrial Revolution in the easiest and clearest way possible.
Meanwhile, a revised edition has been published, examining the present transformed by the waves of the Fourth Industrial Revolution, sketching the future, reflecting changing scientific and technological trends, and including the latest content, including generative AI.


Having covered the scientific field for a long time, the author now meets teenage readers through many lectures and hears diverse voices directly.
Based on that voice , we have revised the book to address the areas that teenagers are truly curious about, and to summarize the qualities and abilities that future talents should cultivate, as well as useful information to know before choosing a career path and major.


In the era of artificial intelligence, where analysis and creation are possible, a deep understanding of AI will become an essential requirement for future talent.
Only then can teenagers find their place in the battle for jobs over AI.
Rather than being swept away by the ever-accelerating waves of technological change, it has become increasingly important to learn how to ride the wave of technology by acquiring more robust human values.
The author, who has long covered the human role and needs of the tech landscape, also guides teenagers on the crucial skills they need to develop in the digital future.
This is why teenagers who will lead the ever-changing digital future should read this book over and over again.

Unique human values, a sense of humanities!
Now we need to read computer science and humanities together!
The most vivid picture of the 4th Industrial Revolution told to young people by a current science journalist.
A story about artificial intelligence, robots, software, and the future of life!

The term '4th Industrial Revolution', which is emphasized in various media, is no longer an unfamiliar word.
After the match between Lee Sedol and AlphaGo, people intuitively felt that artificial intelligence technology would change the future faster than expected.
Countless books and articles related to the Fourth Industrial Revolution are being published, and the term "Fourth Industrial Revolution" is even included in the titles of self-improvement courses.
While interest in the Fourth Industrial Revolution has grown, the pace of development in artificial intelligence is progressing at a rate that exceeds expectations.
People seem to be more fearful than excited about the rapid technological changes that are difficult for humans to keep up with.
There is a growing concern that I will be left behind by the changes brought about by the Fourth Industrial Revolution.


Young people entering the world during this period of rapid change also feel a vague sense of anxiety.
They say that many human jobs will disappear in the future, so I'm worried about which career path I should choose right now.
In a world driven by cutting-edge technology, there is confusion as to whether it is still appropriate to study Korean, English, and math.
Many books about the digital future only tell us about the changes that will occur in the future, but do not tell us what to do and prepare for right now.
This vagueness deepens the anxiety and worries of young people about the future.


This book provides teenagers with the most vivid and clear picture of the future and science and technology brought about by the Fourth Industrial Revolution in an easy-to-understand manner.
It explains the core science and technology of the future through various illustrations and examples.
It also vividly portrays the changes in life and careers that the technology brings and its impact on young people.
Technologies we've only heard about but haven't yet fully grasped—artificial intelligence, robotics, the Internet of Things, big data, interfaces, and communication technologies—are explained in a way that's accessible to teenagers. From the origins of the first computers to the current state of the art, the history of computer science will be told like a fascinating storybook.
It provides the most vivid and realistic reality to teenagers who are curious about what the Fourth Industrial Revolution is and how the digital future will unfold.
This is the first digital humanities book that young people encounter, and it will help them develop an eye for reading future trends.

Uncovering the four critical technologies driving the Fourth Industrial Revolution!
In the AI ​​era, learn about the essential skills young people must cultivate!

The author's focus on explaining difficult digital science knowledge to teenagers in an engaging way that connects it to their lives was greatly influenced by his encounters with young people during lectures.
Having covered Korea's first humanoid robot, Hubo, for over 10 years and witnessed the development of cutting-edge technology up close, the author realized through countless lectures that the "misunderstanding and anxiety about future digital science and technology" among the young people he met was greater than expected.
Young people need 'accurate digital science information' to see AI as a useful tool rather than a competitor to humans.
This book aims to help young people develop a vision for the future and develop their strengths.


Starting with the story of 'Industry 4.0', the predecessor of the Fourth Industrial Revolution, we explain four core technologies that can be seen as central to this revolution.
It explains the nature of these technologies, which are artificial intelligence, data, interface, and communication technology, in an easy-to-understand way.
This alone will allow teenagers to clearly see the future changes that the Fourth Industrial Revolution will bring.
This will be a great help to teenagers who are concerned about their future career paths, as it vividly shows promising future jobs based on this technology.


We also examine from a humanistic perspective how technology has changed jobs and what human values ​​and areas of life will be filled in place of jobs replaced by robots.
We also discuss current measures for coexisting with robots, such as robot taxes and basic income.
This will also give young people the opportunity to think about how humans and technology can work together.
We also explore the essential qualities that young people need to develop in the age of science, technology, and creativity.
It may provide useful information and assistance to teenagers who are struggling to discover their future self-worth.
