Shivon Zilis, a prominent artificial intelligence expert at Neuralink, has been open about her decision to have children with Musk. As revealed in Walter Isaacson's biography Elon Musk, she stated, "He really wants smart people to have kids, so he encouraged me to. If the choice is between an anonymous sperm donor or doing it with the person you admire most in the world, for me that was a pretty f--king easy decision."
Zilis announced the birth of Seldon Lycurgus on X, saying, "Discussed with Elon and, in light of beautiful Arcadia's birthday, we felt it was better to also just share directly about our wonderful and incredible son Seldon Lycurgus."
While Musk has not publicly addressed the paternity claim, his response to Zilis' announcement was a simple heart emoji. As his family continues to grow, Musk's personal life remains a subject of public interest.
