If people don't have to eat, then I estimate that the world is not far from destruction. Getting food is the motive force for human survival, eating is the foundation for human survival, and food is the savior of human soul. If there is no demand for food, then human beings will have no pursuit of existence.

Human civilization is based on the threat of hunger. We can look at the development of various places in the history of the world. Where food is poor, animal people tend to appear, and where food is abundant, lazy people tend to appear. Only where food can meet certain needs, but it is often threatened, will a splendid civilization be born.

Take China as an example. Ancient China was born in the Yellow River valley, where there is fertile land. However, at the beginning of civilization, there were not many food resources available in the wild, and people have been struggling on the hunger line, so the primitive agricultural civilization was established, and then the city-state appeared, which eventually evolved into a country. When people joined the human race, they did not need to eat, and the first step of civilization evolution would be strangled, and all subsequent things would be gone.

Primitive wars were mostly around food. Because of the war, the technology of making utensils and smelting metal began to develop, and because of the demand for resources by technology, the resource battlefield developed, and human beings continued to make progress in the constant consumption of war. It can be said that war is the mentor of human scientific and technological progress, and all this originated from food.

Of course, it is also possible that the explosion of science and technology after human beings will make people have more abilities now, so that we no longer need to rely on food. In the future, people may not eat, but once we are free from food restrictions, this society may disintegrate. Many parts of the existing world economic system are concentrated on the food level, and human beings don't need to eat, so the food production and catering system will collapse directly, which will subsequently affect logistics, transportation, chemical production, construction and other industries. This is a chain, and our society is built on the food system. Changing the social operation mechanism will inevitably support a higher price.

Even if we can bear the danger brought by social changes, there is a bigger problem to be solved urgently, that is, the unemployed people who have left their jobs that have disappeared, society can't provide so many jobs. Although they no longer have to worry about survival, they have to strive for more resources for spiritual satisfaction. If they can't be solved in a limited way, social conflicts will have more serious consequences after they break out. There may be two directions in this matter. One is to consume the population and change the political structure through war. The second is to convict the unemployed, centralize custody and restrict freedom. We don't want to accept both.

Good food can make people happy. For modern people who have no worries about food and clothing, food is not just for survival, we need the feeling of stimulating taste buds, and we need to share the happiness of food, so no matter how the society progresses, please don't deprive us of the right to enjoy good food.
