It is said to be responsible for the depersonalization (使失去个性) of the individual, for stripping (夺去) creativity from human behavior, and for creating massive threats to the species through the development of nuclear power, insecticides, and polluting machinery. If we analyze the situation we can see that it was not the original intent of the people who developed computers to debase humankind, nor was mass production proposed as a method to crush creativity.
