Why So Many Children? Musk’s Views on Population and Parenting

Elon Musk has been very vocal about his concerns over declining birth rates, especially in developed nations. He often states that “civilization is going to crumble” if people don’t have more children. Musk believes that low birth rates pose a major threat to humanity’s future.

His views on reproduction are closely tied to his long-term vision of humanity as a multiplanetary species. In several interviews, Musk has mentioned that he’s trying to “do his part” by having more children.

Despite his busy schedule as a CEO of multiple companies, Musk claims he tries to spend time with his children and provide them with intellectual freedom and opportunities. He reportedly founded the Ad Astra school, later known as Astra Nova, for his children and a few other select students.

Parenting in the Spotlight: Public and Private Dynamics

Although Musk is outspoken in many areas of his life, he remains relatively private about his children. He shares only occasional glimpses of his family life through social media or public events.

Some of Musk’s older children live quiet lives away from the media, while others, like X and Y, occasionally make public appearances. Grimes has spoken publicly about co-parenting with Musk, referring to their relationship as “fluid.”

In contrast, Musk’s relationship with his daughter Vivian is reportedly estranged. Vivian’s legal petition in 2022 included a request to no longer be associated with Musk in any way.
