Inside the Enigmatic World of Tau Techno Mechanicus and Elon Musk’s Unconventional Family
Elon Musk, the polarizing billionaire behind Tesla and SpaceX, has never shied away from making headlines—whether for unfulfilled promises, like his $6 billion pledge to end world hunger, or for public stances that spark controversy.
Yet, nothing quite prepared the world for the revelation of his third child with Canadian musician Grimes (Claire Boucher): a boy legally named Techno Mechanicus Musk, affectionately nicknamed “Tau.” The disclosure, tucked within Walter Isaacson’s 2023 biography Elon Musk, sent the internet into a frenzy, with reactions ranging from disbelief to outright mockery.
This is the story of Tau, the Musk-Grimes family saga, and the quirky naming traditions that keep the world talking.
The Secret Child Revealed
Tau Techno Mechanicus entered the world in June 2022, but his existence remained under wraps until Isaacson’s biography hit shelves in September 2023.
The news broke like wildfire, with Musk confirming Tau’s name on X, writing, “Tau Techno Mechanicus. Circumference/Diameter,” a nod to the mathematical constant tau (twice pi). Grimes, too, chimed in, expressing her desire to shield her son from the public eye. “I wish I could show u how cute little Techno is,” she posted, adding, “but my priority rn is keeping my babies out of the limelight.”
The revelation pushed Musk’s known child count to 11, though later reports suggested his family had grown to 14. With children from multiple partners, including ex-wife Justine Wilson, Neuralink executive Shivon Zilis, and now author Ashley St. Clair, Musk’s sprawling family tree is as complex as his business ventures. His lighthearted reference to his children as a “legion” only fueled public fascination with his unconventional approach to fatherhood.
Why “Tau Techno Mechanicus”?
Musk and Grimes are no strangers to eccentric naming. Their first child, X Æ A-Xii (originally X Æ A-12), sparked debates over pronunciation and legality. Their daughter, Exa Dark Sideræl, nicknamed “Y,” carries a name inspired by computing terms and cosmic phenomena. Tau Techno Mechanicus fits this mold, blending nerdy references with a futuristic flair.
The nickname “Tau” derives from the Greek letter representing 6.28, a number tied to Musk’s June 28 birthday. But fans of Warhammer 40,000 speculate deeper roots: “Tau” is an alien race, and “Mechanicus” evokes a technology-worshipping sect.
Critics on X and Reddit called the name a shallow attempt at geek cred, with one user joking, “It sounds like a Harry Potter spell.” Others worried about Tau’s future, predicting bullying or awkward dating scenarios. “I just feel bad for any future girlfriends,” one Redditor quipped.
Grimes, however, sees Tau as extraordinary. In Isaacson’s book, she described him as having “eyes that could just see so deeply into your soul” and likened him to a Vulcan from Star Trek. Despite the public’s skepticism, the name reflects the couple’s shared love for science, technology, and pop culture.
The Internet’s Wild Reactions
The internet wasted no time dissecting Tau’s name. Social media platforms buzzed with memes and hot takes. A viral Reddit thread on r/facepalm captured the mood: “I am still wondering if this is even real,” one user wrote.
Another lamented, “What is wrong with rich people?!” On X, users posted gifs and jokes, with one tweeting, “Sir, Elon Musk made another baby,” alongside a comedic image. The mix of amusement and outrage underscored the public’s fascination with Musk’s larger-than-life persona.
Some defended the couple’s creativity, arguing that unique names reflect their innovative spirits. Others saw it as an extension of Musk’s need for attention, pointing to his controversial antics—like a reported Nazi salute or his vocal political stances—as evidence of a man who thrives on provocation.
Musk’s Growing Family Tree
Musk’s journey as a father began in 2002 with his first son, Nevada Alexander, who tragically died at 10 weeks. With ex-wife Justine Wilson, he had five more children: twins Vivian and Griffin, and triplets Kai, Saxon, and Damian.
With Shivon Zilis, Musk welcomed twins Strider and Azure, daughter Arcadia, and son Seldon Lycurgus. Recently, Ashley St. Clair claimed Musk fathered her son Romulus, alleging he offered $15 million to keep the child private.
With Grimes, Musk shares three children: X Æ A-Xii (“X”), born in May 2020; Exa Dark Sideræl (“Y”), born via surrogate in December 2021; and Tau. Each name carries layers of meaning. “X” nods to the unknown variable, while “Æ” is pronounced “Ash” by Musk. “Exa” refers to exaFLOPS, a computing term, and “Sideræl” evokes deep space. Grimes has shared quirky details about their kids, like Y’s love for techno music and X’s fascination with rockets.
The Musk-Grimes Relationship
Musk and Grimes began dating in 2018, debuting at the Met Gala. Their “fluid” relationship produced three children before ending in 2022. Despite their split, Grimes called Musk her “best friend” and emphasized their mutual respect.
She rejected claims of being “dumped,” posting on X, “I bounced. My amazing baby is asleep in my bed beside me, I’m in love.” Their co-parenting dynamic remains unconventional, with Grimes noting that X calls her “Claire” instead of “mom.”
A Family Like No Other
The Musk-Grimes saga, capped by Tau Techno Mechanicus’s reveal, is a blend of innovation, eccentricity, and controversy. Their children’s names—equal parts cerebral and whimsical—mirror their parents’ boundary-pushing ethos.
While the internet may mock or marvel, one thing is clear: Musk’s “legion” is unlike any other family in the spotlight. As Tau grows, shielded from public scrutiny, the world will undoubtedly keep watching, waiting for the next chapter in this chaotic, captivating story.
