Digital natives inhabit a completely digitized world, where digital technology and digital culture have penetrated every field and level of human society, becoming essential components of people's life, work, and learning, and have even changed people's way of life and thinking. In the digital native world, people can more naturally use digital technology to obtain information, connect with others, enjoy entertainment, and pursue work or education, achieving higher levels of digitization, greater efficiency, and better user experience. This book provides a comprehensive and systematic introduction to digital natives based on three logical starting points: "The end point of digital transformation is a digital native world", "The driving force of digital transformation is digital immigrants, while that of a digital native world can only be digital natives" and "Digital natives have grown up now". The book introduces the origin, raw material, and driving forces of the digital world (namely, software, data, and computing power), along with artificial intelligence that gives wisdom to the digital world, blockchain-native Web3, and the metaverse as an integration of digital native achievements. Beyond these technical foundations, it delves into how businesses operate, how trust functions, and how economies are governed in this digital native landscape, offering readers a comprehensive vision of this emerging "native world" and all its interconnected elements.
