The world that I imagine in a few decades, robots will appear that will help people in everything. People will begin to populate the planets of our solar system.
To avoid global warming, people will create floating cities. These cities will be managed by artificial intelligence, and each city will be independent, not dependent on others.
In the future, the ecology will be restored. The energy of coal and gas will be replaced by the energy of the Sun. Hundreds of waste processing plants will appear. All this will contribute to the restoration of the ecology.
There will be no war, there will be no crime, starvation, poverty. Everyone will have a home, education and good health.
