Why is science and technology so much more advanced than ancient times, but cultural achievements are far less than ancient times?

This is a misunderstanding. Culture is a social phenomenon, which is the product of people's long-term creation. At the same time, it is a historical phenomenon and the precipitation of social history. To be exact, culture refers to the history, geography, customs, traditional customs, lifestyle, literature and art, code of conduct, way of thinking and values of a country or a nation. Although it is the product of long-term creation, modern cultural creation still far exceeds that of ancient times. From the third industrial revolution to the fourth industrial revolution, mankind has a history of globalization, and various cultural theories (economics, politics and art) collide with each other, and various traditional customs, values and cultural and artistic lifestyles have undergone earth-shaking changes. For example, the invention of electricity changed our traditional sunset lifestyle. Traditional values have been "shattered" by various ideological trends, impressionist modernism and other painting arts, absurd realistic romanticism and other writing methods, modern legal organizations and moral concepts (such as people and natural people and animals and plants) and even our information-based lifestyle. If ancient culture is developing, then the cultural development of this era is advancing rapidly.
