Feasible Future

This is a traditional science fiction novel. The story takes place in the present. Starting from the birth of the first intelligent life, human society has successively experienced the service industry revolution, the human body revolution, and the final revolution, and finally reached the inevitable result of society. When humans look up at the stars, why does no one look down at the earth? Is it because of despair about the future? Is it because you don't dare to imagine that beautiful world? I want to regain that original belief and bring a different story.
