Elon Musk adds AI to empire of Twitter, Tesla, SpaceX, Neuralink & Boring Company

His newest company, xAI, wants to 'understand the true nature of the universe]

Elon Musk added Wednesday to his already-lengthy resume when he officially introduced his new artificial intelligence company, xAI. 

The 52-year-old executive, born in South Africa, currently has leadership or founder positions at numerous companies in the tech sector. His serial entrepreneurship has helped him build a personal fortune worth roughly $250.4 billion as of Friday, making him the world’s richest person, according to Forbes.

He got his start with Zip2, an online business directory service, and X.com, which later became PayPal, as FOX Business previously reported

Find a closer look at his various businesses below:

xAI

The artificial intelligence (AI) company got unveiled roughly four months after Musk moved to register X.AI as a domestic corporation in Las Vegas. xAI, which has a stated mission to "understand the true nature of the universe," has the tech billionaire steering it, according to its website.

Team members at xAI "have previously worked at DeepMind, OpenAI, Google Research, Microsoft Research, Tesla, and the University of Toronto," the company said.

While Musk has expressed concerns about AI and encouraged regulation, he has also indicated a "maximum truth-seeking" AI chatbot was a tool he was interested in building. 

Twitter

Musk ran Twitter as CEO for roughly seven months after buying the platform for an eye-popping $44 billion last year and taking it private.

In that time, he brought numerous product changes like an edit button and a 25,000-character limit for tweets that users must now pay $8 per month to get access to along with a blue verification badge. The company’s headcount has also been trimmed by roughly 6,000, he has said.

In early June, when former NBCUniversal executive Linda Yaccarino took on the title of Twitter’s CEO, he switched to "overseeing product, software & sysops" as executive chair and CTO.

Tesla

The tech billionaire’s tenure at Tesla has spanned nearly 15 years so far.

Boring Company

The Boring Company aims to reduce traffic and "transform" cities, something it aims to do via building transportation, utility and freight tunnels, according to its website. 

There, the Musk-founded company lists a few projects – including its Las Vegas Convention Center Loop, a research-and-development tunnel in Hawthorne, California, and a hyperloop test track – as having been completed. The "Vegas Loop" under the Strip and a tunnel connecting Resorts World Las Vegas to the convention center are still in the works.

Last year, the flamethrower-selling company offered a "Burnt Hair" perfume, over 10,000 of which were sold, FOX Business previously reported.
