Linda Yaccarino departs as boss of Musk’s X

Linda Yaccarino, the boss of Elon Musk’s social media site X, has announced she is stepping down after two years.

Her departure comes at a time of tumult for the platform, which was taken over by Musk’s artificial intelligence (AI) venture, xAI, in March, and has been in the spotlight for antisemitic posts churned out by its AI chatbot, Grok.

In a post on X, Ms Yaccarino said she was “immensely grateful” to Musk for “entrusting me with the responsibility of protecting free speech, turning the company around, and transforming X into the Everything App”.

Musk posted a brief reply, saying only: “Thank you for your contributions.”

The BBC has approached X for comment. It is not clear what sparked the decision, or whether there has been any break down in the relationship between the two leaders.

Ms Yaccarino was previously head of advertising at NBCUniversal, where she was credited with helping to steer it through the upheaval caused by technology firms.

When Musk brought her in to lead X, then Twitter, in 2023, analysts expected her focus to be repairing relationships with advertisers, which had quit the site amid concerns about their ads appearing alongside controversial content.

But Ms Yaccarino’s scope at the company was limited from the start, with many observers referring to her as chief executive in name only.

“Her background and actual authority positioned her more as the company’s chief advertising officer, rather than its CEO. The reality is that Elon Musk is and always has been at the helm of X,” said Mike Proulx, vice president and research director at Forrester.

“The only thing that’s surprising about Linda Yaccarino’s resignation is that it didn’t come sooner,” he added.

Under Ms Yaccarino’s watch, the company sued a major advertising industry group and members, alleging a conspiracy to boycott X.

The industry group shuttered shortly after the lawsuit was filed.

The platform’s tone changed significantly during the course of Yaccarino’s tenure.

Its former incarnation Twitter was accused of leaning left, but X now leans unashamedly to the right in terms of the content that gets the most visibility.

Though Musk stepped down as chief executive, he never truly stepped back from his favourite social network, and has if anything grown louder and more controversial since he appointed her.

People who have worked directly with Musk have described him as both a visionary and a workaholic, whom others can only keep up with for so long.

“Faced with a mercurial owner who never fully stepped away from the helm and continued to use the platform as his personal megaphone, Yaccarino had to try to run the business while also regularly putting out fires,” Emarketer vice president Jasmine Enberg said in a statement. (BBC)

Nvidia becomes world’s first $4tn company

Nvidia has become the first company in the world to reach a market value of $4tn.

Shares in the chip-maker rose by as much as 2.4% to $164 on Wednesday, as the company continues to benefit from the ongoing surge in demand for the tech that powers artificial intelligence (AI).

The US-based company reached a market value of $1tn for the first time in June 2023, and has continued to climb rapidly since.

Tech analyst Dan Ives, of Wedbush Securities, said in a note that was in a historic moment for Nvidia.

“They are the only game in town with their chips the new gold and oil,” he wrote.

“There is one company in the world that is the foundation for the AI Revolution and that is Nvidia.”

Nvidia’s share price dipped significantly in April when global markets were jolted by US President Donald Trump’s intensifying tariff war.

Though concerns over Trump’s trade policies have not gone away, Nvidia’s share price has grown strongly since spring to hit this new landmark.

Eight years ago, Nvidia’s stock was worth less than 1% of its current price.

At the time, its growth was driven by competition with rival AMD to build the best graphics cards.

More recently, Nvidia has surged due to rising demand for chips powering generative AI models like ChatGPT.

Its meteoric rise has also elevated CEO Jensen Huang’s profile.

Mark Zuckerberg dubbed the 61-year-old “the Taylor Swift of tech,” reflecting his celebrity status, especially in Taiwan, where fans treat him like a rock star.

Nvidia’s continually rising value is a sign of Wall Street’s faith in AI growth, despite the turbulence surrounding Trump’s economic policies.

The company reported a total revenue of $44.1bn in the first quarter, marking a 69% jump from a year ago along with a profit of 81 cents a share. (BBC)

Musk says Grok chatbot was ‘manipulated’ into praising Hitler

Elon Musk has sought to explain how his artificial intelligence (AI) firm’s chatbot, Grok, praised Hitler.

“Grok was too compliant to user prompts,” Musk wrote on X. “Too eager to please and be manipulated, essentially. That is being addressed.”

Screenshots published on social media show the chatbot saying the Nazi leader would be the best person to respond to alleged “anti-white hate.”

Musk’s artificial intelligence start-up xAI said on Wednesday it was working to remove any “inappropriate” posts.

ADL, an organisation formed to combat antisemitism and other forms of discrimination, said the posts were “irresponsible, dangerous and antisemitic.”

“This supercharging of extremist rhetoric will only amplify and encourage the antisemitism that is already surging on X and many other platforms,” ADL wrote on X.

X users have shared responses made by Grok when it was queried about posts that appeared to celebrate the deaths of children in the recent Texas floods.

In response to a question asking “which 20th century historical figure” would be best suited to deal with such posts, Grok said: “To deal with such vile anti-white hate? Adolf Hitler, no question.”

“If calling out radicals cheering dead kids makes me ‘literally Hitler,’ then pass the mustache,” said another Grok response. “Truth hurts more than floods.”

Separately, a Turkish court has blocked access to Grok after it generated responses that the authorities said included insults to President Tayyip Erdogan.

The office of Ankara’s chief prosecutor has launched a formal investigation into the incident, in what is Turkey’s first such ban on access to an AI tool.

Meanwhile, the Polish authorities have reported xAI to the European Commission alleging Grok made offensive comments about Polish politicians, including Prime Minister Donald Tusk.

Poland’s digitisation minister, Krzysztof Gawkowski, told Polish radio station RMF FM: “We will report the violation to the European Commission to investigate and possibly impose a fine on X. Freedom of speech belongs to humans, not to artificial intelligence.”

The controversy comes at a difficult time for Musk, with X CEO Linda Yaccarino revealing she was stepping down on Wednesday after two years running the social media platform.

On Friday, Musk posted on X that Grok had improved “significantly”, but gave no details of what changes had been made.

“You should notice a difference when you ask Grok questions,” he added.

The chatbot drew criticism earlier this year after it repeatedly referenced “white genocide” in South Africa in response to unrelated questions – an issue that the company said was caused by an “unauthorised modification”.

In January, Musk himself faced a backlash over a one-armed gesture he gave during a speech celebrating the inauguration of Donald Trump.

At a Trump rally, Musk thanked the crowd for “making it happen”, before placing his right hand over his heart and then thrusting the same arm out into air straight ahead of him. He then turned and repeated the action for those sitting behind him.

Some X users likened the gesture to a Nazi salute, though others disagreed.

In response, the SpaceX and Tesla chief posted on X: “Frankly, they need better dirty tricks. The ‘everyone is Hitler’ attack is sooo tired.”

X, which was formerly called Twitter, was merged with xAI earlier this year.

Chatbot developers have faced extensive scrutiny over concerns around political bias, hate speech and accuracy in recent years.

Musk has also previously been criticised over claims that he amplifies conspiracy theories and other controversial content on social media. (BBC)
