If there were no major disasters on the earth, what would happen in 500 years according to the speed of scientific and technological progress of mankind today?

It is hard to say what the world will be like in 500 years, because people 500 years ago could not imagine the world now. Even 50 years ago, you could ask your grandparents if they would believe that shopping and payment, the two most common things in our lives, could be done on mobile phones.

However, human beings have dreams and like daydreaming most. Therefore, we also boldly speculate on the world in 500 years.

① Immigrating to Mars

Immigrating to Mars is an ambition of mankind. I don't know if you have seen a movie-Alien Battlefield, which is very wonderful. Although the sense of science and technology is slightly insufficient, we should know that the author was 100 years ago, and his imagination is against the sky. Therefore, what we think today is not necessarily impossible in the future.

Moreover, there is a "madman" who is already implementing the "Martian immigration" plan. Musk, the head of Tesla, has done many things that even the country can't. He will be the pioneer of the future. 500 years later, there will be a statue of him on Mars, which is admired by Martian immigrants.

② Most countries have disappeared.

In the future, most countries will definitely disappear, and the earth country may not be realized, but the States will be unified. Because Asia is too big and adjacent to Europe, East Asia, Southeast Asia and South Asia are unified, and West Asia and Europe are unified.

The United Nations will disappear, and there is no need for this Organization to exist. Instead, it will be the joint parliament of five continents, oh no, five big countries. The daily work of the joint parliament is to coordinate contradictions between countries and international trade. Of course, there are occasional small frictions between regions, but we all know that cooperation can be mutually beneficial. When all continents become a country, resources are not so scarce.

(3) Humans will get rid of the bondage of energy.

In The Wandering Earth, the earth is driven by burning stones. In the future, oil and coal will definitely become the past, and even nuclear power will be eliminated. Humans will certainly find cleaner and safer energy, thus realizing energy freedom. This will also promote the development of human science and technology to the universe. After all, with enough energy, we can better support human ambitions and let a large number of people and materials leave the earth and appear on Mars.

In fact, oil and coal are not as little as everyone thinks. According to the current exploitation amount, it will not be exhausted even after another hundred years.

(4) Human beings will live forever.

The development of biotechnology and mechanical technology will certainly merge together, and then human beings will realize their dream of immortality. Although we have the ability to live forever, the population will decline and be replaced by a large number of biotechnologists with human cells. They don't need to consume food, but they can use new energy to provide a steady stream of labor for mankind.

Just like the creator of that year, human beings created new life forms based on their own body data. At that time, human beings will boast that they are protoss and supreme beings.

As for the replacement of human beings by intelligent robots in science fiction films, it will not happen yet, because human beings only give them bodies and simple thinking, and they will not have self-awareness. The brain is too complicated, and 500 years of human technology can't reach the level of making brains. Although we can immigrate to Mars, we still can't leave the solar system.

Maybe a thousand years later, or even longer, when human beings can create a self-conscious life, they can really get in touch with the real world, and our present world is probably just a game of "God".
