However, he himself has little father responsibility in the process of children's growth. < / P > < p > musk said a few days ago that people must follow his example and put maintaining the population first. He said: "There is still not enough population. If people don't have more children, civilization will collapse." < p > many data do show that Musk's warning is reasonable. Like Britain, the fertility rate in the United States has been lower than the "replacement level" and will further decline by 4% in 2020. But it is uncertain whether this means disaster or what measures musk and others can take to deal with it < p > plans to increase the birth rate often conflict with plans to educate girls: generally, the more educated women are, the fewer children they have on average. British survey shows that although parents usually like more children, research also shows that childbearing has a limited impact on parents' happiness and life satisfaction < p > musk also did what he said and tried to set an example in fertility < p > but how does musk take into account the needs of six children while operating Tesla, SpaceX and other businesses at the same time? Will he finish the catering plan and cooking next week on Sunday like super mother? Let the children cry < p > in this regard, musk admitted that because the baby is "just a machine for eating and defecating", his former partner and singer Grimes played a "more important role" in taking care of the sixth child. Musk admitted: "there is nothing I can do now. But when the child grows up, I will play more roles." < p > musk had five children with his first wife, writer Justine Wilson. He once said: "if I visit China, I will take my children to see the Great Wall, or take the high-speed railway from Beijing to Xi'an to see the terracotta warriors and horses." However, Wilson said: "musk is absorbed in his work. Even at home, his mind is elsewhere." < p > in this regard, time does not seem to have changed musk much. When discussing his lifestyle choices with the public, musk himself said: "it would be great if I had more free time instead of just working day and night." (small) < / P > < p >
