In the future, society's productive forces have developed to an extraordinary degree, and technology has advanced by leaps and bounds. Artificial intelligence has completely replaced human labor. With the help of high-tech devices, people can gain a largely objective understanding of their abilities, make full use of their strengths, and ensure that everyone can contribute according to their abilities and get what they need. Only a higher level of morality can sustain the development of a more advanced civilization. Differences in productivity and technology also lead to differences in how people think. This book tells the story of a society full of such possibilities.
