Shivon Zilis, a Neuralink executive and mother of four of Musk's children, announced the end of their relationship on X, expressing mixed feelings and hopes for friendship. Meanwhile, Musk’s other confirmed partners, Justine Wilson, Grimes, and Ashley St. Clair, have publicly discussed their experiences with him, with St. Clair revealing she rejected a $40 million nondisclosure agreement. Both Wilson and St. Clair appear in a new documentary about Musk, offering critical perspectives on his rise in Silicon Valley.
Elon Musk announced that his artificial intelligence division, originally called SpaceXAI, will now be named SpaceXSI, with 'SI' standing for 'super intelligence.' The change was made after a social media prompt from a fan referencing a suggestion by President Donald Trump. Musk emphasized that the new name omits 'AI' in favor of 'SI' for a more impactful branding.
Elon Musk said Tesla extended its Austin robotaxi operating hours from 10pm to 11pm, explaining the limit exists to avoid hitting pets that are hard to see at night, specifically citing grey kittens on grey pavement. Tesla relies solely on cameras for its self-driving system, forgoing the radar and LIDAR sensors used by rival robotaxi operators.
Elon Musk confirmed on X that SpaceXAI, the division formed after SpaceX acquired xAI, will be renamed SpaceXSI. The move follows President Trump's executive order directing US government agencies to replace the term 'artificial intelligence' with 'Super Intelligence' in official communications. As of this report, SpaceXAI's website and X account still carry the old name.
A critique argues that the AI industry's foundational assumption—that the human brain operates like a computer processing input, computation, and output—oversimplifies human cognition. The piece traces this model back to Alan Turing and notes that even computing pioneer John von Neumann doubted computational models could capture the full complexity of the human nervous system. The author contends that as AI products become more embedded in daily life, this flawed mental model is causing real problems.
Elon Musk confirmed on X that discussions are underway with TSMC about a potential collaboration tied to his Terafab chipmaking initiative, saying 'something may come of it.' According to Tim Culpan's Culpium newsletter, the most likely arrangement would have TSMC own and operate a new fab serving only Tesla, SpaceX, and xAI, with SpaceX/Terafab possibly investing or committing to chip purchase volumes; a less likely alternative would give SpaceX majority ownership with TSMC providing operational and process expertise.
Tesla has increased the number of its driverless Cybercab vehicles authorized for commercial service in Texas to nearly four times the count at launch a month ago. Riders have reported issues including long wait times, incorrect pickup and drop-off locations, and malfunctioning butterfly doors and trunks since the September 3 debut in Austin.
TIME magazine reports that during a December 2025 Oval Office meeting, Trump questioned Elon Musk's Grok chatbot for hours about Venezuela and whether Venezuelans would welcome the capture of president Nicolas Maduro. Grok reportedly told him Maduro was deeply unpopular and that his removal would be celebrated, and Trump subsequently ordered military strikes that killed dozens of Venezuelan and Cuban personnel and some civilians, resulting in Maduro's capture.
Tesla delivered more than 486,000 vehicles in the third quarter, up about 6,000 from the prior quarter and ahead of Wall Street forecasts. The figure still trails the 497,000 delivered a year earlier, when buyers rushed to beat an expiring U.S. tax credit, and U.S. deliveries were down nearly 20% year-over-year according to Cox Automotive.
Shivon Zilis revealed her separation from Elon Musk by retweeting a post indicating Musk was no longer following her on X. She described the breakup as sudden and emotionally difficult, sharing her feelings publicly. Zilis also has a history of working closely with Musk on his AI ventures and was involved in legal disputes related to Musk's donations to OpenAI.
Tesla reported 486,532 vehicle deliveries and 464,391 units produced in the third quarter, exceeding analyst forecasts of roughly 461,000-462,000. Deliveries were down about 2% from a year earlier but rose from the second quarter's 480,126, with Model 3 and Model Y making up 98% of the total. Tesla shares rose about 2% after the announcement.
In a documentary, Justine Musk accused Elon Musk of referring to mothers of his children as 'breeders' and described her own departure from his life. Meanwhile, Shivon Zilis, Musk’s former partner and mother of four of his children, posted a cryptic message on social media indicating her breakup with Musk after five years. The details highlight ongoing personal disputes involving the billionaire and his family.
