Elon Musk and Grimes Welcome Their Third Baby, Tau Techno Mechanicus

Elon Musk, the billionaire in the tech industry renowned for founding companies like Tesla, SpaceX, and X, has recently confirmed the birth of his third child with his former partner, Grimes, the Canadian singer and producer.

Their new son has been named Tau Techno Mechanicus, which follows the unconventional trend set by their previous children, X Æ A-Xii and Exa Dark Sideræl Musk, born in 2020 and 2021 respectively. In this blog post, we’ll delve into the significance behind the baby’s unique name, provide details about his birth, and shed light on the current status of his parents’ relationship.

What Does Tau Techno Mechanicus Mean?

The name Tau Techno Mechanicus draws inspiration from the realms of science fiction and fantasy. Tau, the 19th letter of the Greek alphabet, is also the name of an extraterrestrial species featured in the Warhammer 40,000 universe—a widely popular tabletop game and media franchise.

Meanwhile, Techno Mechanicus references the cult of technology enthusiasts within the same fictional universe, known as the Adeptus Mechanicus. Interpretatively, this name could pay tribute to Musk’s deep-rooted interest in science and technology, as well as Grimes’ artistic inclinations spanning various genres and forms of media.

When and How Was Tau Techno Mechanicus Born?

The existence of Tau Techno Mechanicus remained a well-guarded secret until a recent announcement by Musk on X (formerly Twitter) on September 11, 2023. Although the precise date and location of his birth remain undisclosed, it is likely that he came into the world in early 2023 or late 2022.

According to a newly released biography by Walter Isaacson on September 12, 2023, Musk and Grimes used in vitro fertilization (IVF) to conceive their first child, X Æ A-Xii. It is plausible that they followed the same approach for their subsequent two children.

What Is the Current Relationship Status of Elon Musk and Grimes?

Musk and Grimes, whose real name is Claire Boucher, initiated their relationship in 2018 after crossing paths online through a jest about artificial intelligence. They made their first public appearance as a couple at the Met Gala in May 2018. Although they parted ways in September 2021, they maintained an amicable relationship, co-parenting their children.

Grimes has described their relationship status as “very fluid” and has expressed mutual affection. In a March 2022 interview with Vanity Fair, she disclosed that their second child, Exa Dark Sideræl Musk, was born via surrogate in December 2021. Interestingly, they had no intention of announcing the birth of their second child (nicknamed “Y”) but did so inadvertently when a journalist overheard a baby crying.


Elon Musk and Grimes stand out as one of the most unconventional and captivating celebrity couples of recent times. They have consistently surprised the world with their distinctive baby names and discreet pregnancies. Moreover, they have demonstrated their ability to maintain a friendly and adaptable relationship, despite their hectic and demanding careers. As they venture into their future endeavors, we extend our warmest congratulations to them on the arrival of their third child, Tau Techno Mechanicus.
