Elon Musk, CEO of Tesla and SpaceX, welcomed his third child with Neuralink executive Shivon Zilis earlier this year. Musk, who has been vocal about declining birth rates, now has at least 12 children. This news comes amidst reports of Musk's relationships with female employees at SpaceX, which have been criticized. Despite global population growth surpassing eight billion, Musk continues to warn of a population crisis, particularly in affluent countries. While birth rates are declining in some countries, immigration is offsetting these declines in others. Musk's concerns about underpopulation and demographic suicide continue to drive his advocacy for people to have more children. The report highlights the complexities of global population trends and the impact of wealth and education on birth rates. This news underscores Musk's dual role as a tech mogul and a proponent of increasing the global population.
