American probes discovered the ocean on Ceres. Will future space migration come true?

Space migration can be realized now, but if you want to emigrate on a large scale, I don't think you can.

According to the current level of science and technology, it is entirely possible to immigrate some people to live in space. All you need is a vehicle that can send people into space, a steady stream of food and enough oxygen. How many countries can meet this requirement now? Countless but large-scale immigration is impossible and unnecessary. Just like last year's hottest sci-fi movie Wandering Earth, the elite strategy embodied in it is also the most real and most likely to be realized in real life.

Suppose the earth is in trouble, people have to emigrate to outer space, and the number of people on board is limited. If people who leave the earth earlier are more likely to survive, who will be the first to be sent away? There is no denying that it must be those who have power, money and ability. But these people are a minority among the people of the world and are in line with the elite strategy. In this order, immigrants from outer space are elites. If there are large-scale immigrants, the number of people that can be accommodated in outer space must be limited. Aside from these, the economic cost and transportation cost of sending people into space are so high that every country can't afford it now, not because of money, but because of resources. Money is only a measure of value. To put it bluntly, it is paper itself, and flying into space depends on resources. The resources on the earth are very limited, and so are the productivity and scientific and technological level. Some people calculate that a person will be sent into space.

Who can feed ordinary people? Therefore, large-scale immigration into space will not be realized for the time being, unless spacecraft becomes the most convenient means of transportation, and resources, rather than money, are deposited in banks. As far as the present situation is concerned, it is far from being realized. So, start working hard now and let yourself surpass others, so that even if the world ends, the country will save you first.
