Dramatic insider warnings over AI fall flat with some in Silicon Valley

Key points

• Anthropic was valued at $965bn (£713bn) in its most recent fundraising round earlier this year.
• Federal legislation co- this month by left-wing Senator Bernie Sanders of Vermont, known as the Ban Artificial Superintelligence Act, would impose a temporary pause in advanced AI development.
• One conference speaker, Grindr CEO George Arison, informed the BBC he believed this week's comments from Coxon and others were indicative of an "anti-civilisational worldview at Anthropic".
• Brad Gerstner, who is the head of the investment firm Altimeter Capital, posted pictures of Huang from the conference and accused Coxon of "ridiculous hyperbole".
• On Friday, the CEO of the AI platform Hugging Face, Clement Delangue, weighed in.

Each September, a who's who of executives from throughout Silicon Valley descends on San Francisco's Palace Hotel to charm investors at a conference hosted by the investment bank Goldman Sachs.

This past week, between talk of expansion and potential returns, tech titans identified themselves addressing the abrupt resignation of Anthropic researcher Jacob Coxon.

Coxon, a 27-year-old who worked at OpenAI before joining its chief rival Anthropic, remarked on Tuesday that residents building artificial intelligence (AI) believed the technology could destroy humanity.

They are "gambling with our lives", he remarked, "these will soon be superhuman systems that can hack anything".

Coxon is by no means the first AI insider to publicly sound the alarm. There have been a string of high-profile resignations from both Anthropic and OpenAI over recent years over apparent safety reservations, and some current Anthropic employees even echoed Coxon's post.

"We really do earnestly believe AI could kill all humans! I personally think it is >10% within the next decade, " a team lead at Anthropic, Evan Hubinger, posted on X.

While Coxon remarked explicitly in his posts that his warnings were "not marketing", some executives and investors in Silicon Valley have reacted with scepticism to a recent flurry of insiders sounding the alarm.

Anthropic and OpenAI are reportedly preparing for potentially record-setting initial public offerings, and some in the tech sector have suggested the latest stark comments regarding the dangers of AI may be designed to generate hype by signalling the power of these products.

Anthropic's boss, Dario Amodei, has come under fire for saying AI technology could wipe out half of entry-level white-collar jobs and will "test who we are as a species".

He called them "dangerous" and remarked they had prompted him to instruct some engineers at the LGBTQ+ dating app to stop using Anthropic's technology.

"It is irresponsible for us as stewards of our shareholders' money to be relying on a business that does what this company does, in terms of its public statements, " he remarked.

"Maybe they actually believe it, " Arison remarked. "Or you could argue they're saying it because it's a great way to gin up more investor support, because the only way to justify these valuations is to actually claim: 'I'm going to take over every industry and I'm going to take over every job, and my AI is going to be doing all that work.'".

Anthropic was valued at $965bn (£713bn) in its most recent fundraising round earlier this year. The BBC has asked Anthropic for a response to the statements.

In an essay posted early on Saturday, Amodei pressed a slowing of AI model development and global regulation – and stated the risks associated with AI were "serious". Anthropic boss Dario Amodei calls for AI development to slow down.

Anthropic researcher believes more than 10% chance AI 'could kill all humans'. Why some experts increasingly fear AI will take over.

Nvidia boss Jensen Huang additionally discussed Coxon's comments before a crowd at the conference, multiple residents in the group informed the BBC. They remarked he dismissed them as untrue.

Huang has previously remarked the notion that AI "is going to be the end of humanity" is "complete nonsense".

And while he may have a business interest in an AI boom – Nvidia builds chips that power AI systems – his comments reflect a growing backlash in Silicon Valley to the existential warnings from current and former staffers.

Some critics have even accused Anthropic of fearmongering in hopes that it will trigger a regulatory push that could shut out competition and leave it and OpenAI with a duopoly in the sector.

On Friday, the CEO of the AI platform Hugging Face, Clement Delangue, weighed in. Hugging Face, which Nvidia confirmed it would acquire last week, was hacked by OpenAI agents earlier this year prompting an outcry over AI safety.

"Sorry, but asking Jacob about AI extinction risk is like asking your AC guy about climate change, " he wrote on X. "Not saying it's necessarily uninteresting or wrong per se but let's keep things in perspective."

Both Gerstner and Delangue were more circumspect on Saturday after Amodei's proposal was posted, with Gerstner calling the idea "an important step forward" in balancing competing considerations like speed and safety.

Delangue offered to support be a part of the potential solutions proposed by Amodei. Could insider warnings prompt a crackdown?

In April, Anthropic roiled the AI world when it remarked it identified that its Mythos tool could outperform humans at some hacking and cybersecurity tasks.

Mythos additionally demonstrated the ability to independently escape what is known as the sandbox environment, setting off a debate among regulators, legislators and businesses regarding AI's potential dangers.

In a new development on Thursday, Anthropic remarked it had identified and halted threat actors who were trying to apply its AI technology for activity including the development of bioweapons and cyber-espionage.

Beneath the sparkling chandeliers hanging in the stained-glass dome atrium of The Palace Hotel, some investors informed the BBC that the comments from Coxon and others could accelerate a administration crackdown.

"There is a good chance that human beings will lose control over AI, " Sanders informed the BBC's Newsnight programme on Thursday. "And what happens then, nobody knows. But could it be catastrophic? Yes, it could."

"When scientists tell you there is a chance that it could have a cataclysmic impact on humanity, you've got be a moron not to say, slow it down, " he continued.

If an industry-wide administration crackdown comes, even so, it is projected to be led by legislators and not the Trump administration which largely supports a policy of unfettered AI development. It has framed this as necessary to ensure the US does not cede dominance to China.

Speaking to reporters this week, President Donald Trump was asked if he had any reservations concerning AI leading to human extinction. "No, I don't have any, " he remarked. "I have reservations that if we don't win AI, we're going to be put in a highly bad position. We are leading China right now."

But the president's relationship with Anthropic has been turbulent. After the firm refused to allow the US military to apply its AI models, the White House described it as "a radical left, woke company" and designated it a supply chain risk, a move that a federal judge has ruled was illegal.

David Sacks, Trump's AI czar in the early days of his administration, has additionally levelled repeated attacks at Anthropic.

OpenAI has not endured the same level of scrutiny from the White House. When releasing a new model called Astra last week, OpenAI President Greg Brockman described his firm's relationship with the Trump administration as "a very good partnership". The firm did not respond to a BBC inquiry seeking comment.

At the conference in San Francisco this week, the pursuit of fortunes seemed to mostly trump any mounting existential reservations or fears over potential administration restrictions on AI.

OpenAI, which was most lately valued at $852bn, has previously unveiled intends to allow residents to purchase shares in its firm by listing on the stock market.

In short, dramatic insider warnings over AI fall flat with some in Silicon Valley is the central thread here, and readers can expect follow-up reporting as the picture becomes clearer.
