xAI, Elon Musk’s 10-month-old competitor to the AI phenom OpenAI, is raising $6 billion on a pre-money valuation of $18 billion, according to one trusted source close to the deal. The deal — which would give investors one quarter of the company — is expected to close in the next few weeks unless the terms of the deal change.

The deal terms have changed once already. As of last weekend, Jared Birchall, who heads Musk’s family office, was telling prospective investors that xAI was raising $3 billion at a $15 billion pre-money valuation. Given the number of investors clamoring to get into the deal, those numbers were quickly adjusted.

Says our source, “We all received an email that basically said, ‘It’s now $6B on $18B, and don’t complain because a lot of other people want in.”

Humanoid robots have been in development for many years by Japan’s Honda and Hyundai Motor’s Boston Dynamics. Earlier this year, Microsoft and Nvidia-backed startup Figure said it had signed a partnership with German automaker BMW to deploy humanoid robots in the car maker’s facility in the US.

Elon Musk said before that robot sales could become a larger part of the Tesla business. He said, “I think Tesla is best positioned of any humanoid robot maker to be able to reach volume production with efficient inference on the robot itself.”

Meanwhile, Bostrom’s email from the 1990s resurfaced last year and resulted in him issuing a statement repudiating his racist remarks and clarifying his views on subjects such as eugenics. Some of his answers – “Do I support eugenics? No, not as the term is commonly understood” – led to further criticism from fellow academics that he was being evasive.

The university launched an investigation into Bostrom’s conduct following the discovery of his racist email, while other major effective altruism groups distanced themselves from him.

“We unequivocally condemn Nick Bostrom’s recklessly flawed and reprehensible words,” the Centre for Effective Altruism, which was founded by fellow Oxford philosophers and financially backed by Bankman-Fried, said in a statement at the time.

The extended mind — For decades, philosophers have debated the borders of personhood: where does our mind end, and the external world begin? On a simple level, you might assume that our minds rest within our brains and bodies. However, some philosophers have proposed that it’s more complicated than that.


When we merge mind and machine, the traditional borders of the self dissipate, says philosopher Dvija Mehta.

In 2021, he heard about a trial of a visual prosthesis at Illinois Institute of Technology in Chicago. Researchers cautioned that the device was experimental and he shouldn’t expect to regain the level of vision he had before. Still, he was intrigued enough to sign up. Thanks to the chips in his brain, Bussard now has very limited artificial vision—what he describes as “blips on a radar screen.” With the implant, he can perceive people and objects represented in white and iridescent dots.

Bussard is one of a small number of blind individuals around the world who have risked brain surgery to get a visual prosthesis. In Spain, researchers at Miguel Hernández University have implanted four people with a similar system. The trials are the culmination of decades of research.

There’s interest from industry, too. California-based Cortigent is developing the Orion, which has been implanted in six volunteers. Elon Musk’s Neuralink is also working on a brain implant for vision. In an X post in March, Musk said Neuralink’s device, called Blindsight, is “already working in monkeys.” He added: “Resolution will be low at first, like early Nintendo graphics, but ultimately may exceed normal human vision.”
