"Mr. Musk has told people close to him in recent months that he envisions his children (of which there are at least 11) and two of their three mothers occupying adjoining properties."

"That way, his younger children could be a part of one another’s lives, and Mr. Musk could schedule time among them. Directly behind the villa is a six-bedroom mansion.... When in Austin, he often stays at a third mansion about a 10-minute walk away.... One of the mothers, Shivon Zilis, an executive at Neuralink... has moved into one of the homes with her children. But Claire Boucher, the musician better known as Grimes, who is the mother to three of his children, is in a protracted legal fight with Mr. Musk and has so far steered clear. The third mother is Mr. Musk’s first wife, Justine Musk, with whom he has five living children, all in their late teens or older. There is room in the Austin compound if they were to visit, though he is estranged from at least one of those children.... Mr. Musk has said that I.V.F. is a more efficient way of having children because it allows parents to control parts of the process, according to a person who understands his thinking.... In 2021, without Ms. Boucher’s knowledge, Mr. Musk donated sperm to Ms. Zilis, who became pregnant with twins through I.V.F.... That same year, the billionaire and Ms. Boucher were expecting a second child also conceived via I.V.F. but carried by a surrogate.... Further complicating matters, Mr. Musk took a name that he and Ms. Boucher had chosen for their daughter — Valkyrie — and gave it to one of Ms. Zilis’s twins...."

From "Elon Musk Wants Big Families. He Bought a Secret Compound for His. As the billionaire warns of population collapse and the moral obligation to have children, he’s navigating his own complicated family" (NYT)(free-access link).

I wonder what kind of "control" he is doing with IVF.
