AI puts humanity at ‘risk of extinction,’ experts warn

Artificial intelligence

Artificial intelligence could lead to the extinction of humanity, experts - including the heads of OpenAI and Google Deepmind - have warned.

Dozens have supported a statement published on the webpage of the Centre for AI Safety.

"Mitigating the risk of extinction from AI should be a global priority alongside other societal-scale risks such as pandemics and nuclear war" it reads.

But others say the fears are overblown.

Sam Altman, chief executive of ChatGPT-maker OpenAI, Demis Hassabis, chief executive of Google DeepMind and Dario Amodei of Anthropic have all supported the statement.

The Centre for AI Safety website suggests a number of possible disaster scenarios:

• AIs could be weaponised - for example, drug-discovery tools could be used to build chemical weapons
• AI-generated misinformation could destabilise society and "undermine collective decision-making"
• The power of AI could become increasingly concentrated in fewer and fewer hands, enabling "regimes to enforce narrow values through pervasive surveillance and oppressive censorship"
• Enfeeblement, where humans become dependent on AI "similar to the scenario portrayed in the film Wall-E"

Dr Geoffrey Hinton, who issued an earlier warning about risks from super-intelligent AI, has also supported the Centre for AI Safety's call.

Yoshua Bengio, professor of computer science at the university of Montreal, also signed.

Dr Hinton, Prof Bengio and NYU Professor Yann LeCun are often described as the "godfathers of AI" for their groundbreaking work in the field - for which they jointly won the 2018 Turing Award, which recognises outstanding contributions in computer science.

But Prof LeCun, who also works at Meta, has said these apocalyptic warnings are overblown tweeting that "the most common reaction by AI researchers to these prophecies of doom is face palming".

'Fracturing reality'

Many other experts similarly believe that fears of AI wiping out humanity are unrealistic, and a distraction from issues such as bias in systems that are already a problem.

Arvind Narayanan, a computer scientist at Princeton University, has previously told the BBC that sci-fi-like disaster scenarios are unrealistic: "Current AI is nowhere near capable enough for these risks to materialise. As a result, it's distracted attention away from the near-term harms of AI".

Oxford's Institute for Ethics in AI senior research associate Elizabeth Renieris told BBC News she worried more about risks closer to the present.

"Advancements in AI will magnify the scale of automated decision-making that is biased, discriminatory, exclusionary or otherwise unfair while also being inscrutable and incontestable," she said. They would "drive an exponential increase in the volume and spread of misinformation, thereby fracturing reality and eroding the public trust, and drive further inequality, particularly for those who remain on the wrong side of the digital divide".

Many AI tools essentially "free ride" on the "whole of human experience to date", Ms Renieris said. Many are trained on human-created content, text, art and music they can then imitate - and their creators "have effectively transferred tremendous wealth and power from the public sphere to a small handful of private entities".

But Centre for AI Safety director Dan Hendrycks told BBC News future risks and present concerns "shouldn't be viewed antagonistically".

"Addressing some of the issues today can be useful for addressing many of the later risks tomorrow," he said.

Superintelligence efforts

Media coverage of the supposed "existential" threat from AI has snowballed since March 2023 when experts, including Tesla boss Elon Musk, signed an open letter urging a halt to the development of the next generation of AI technology.

That letter asked if we should "develop non-human minds that might eventually outnumber, outsmart, obsolete and replace us".

In contrast, the new campaign has a very short statement, designed to "open up discussion".

The statement compares the risk to that posed by nuclear war. In a blog post OpenAI recently suggested superintelligence might be regulated in a similar way to nuclear energy: "We are likely to eventually need something like an IAEA [International Atomic Energy Agency] for superintelligence efforts" the firm wrote.

'Be reassured'

Both Sam Altman and Google chief executive Sundar Pichai are among technology leaders to have discussed AI regulation recently with the prime minister.

Speaking to reporters about the latest warning over AI risk, Rishi Sunak stressed the benefits to the economy and society.

"You've seen that recently it was helping paralysed people to walk, discovering new antibiotics, but we need to make sure this is done in a way that is safe and secure," he said.

"Now that's why I met last week with CEOs of major AI companies to discuss what are the guardrails that we need to put in place, what's the type of regulation that should be put in place to keep us safe.

"People will be concerned by the reports that AI poses existential risks, like pandemics or nuclear wars.

"I want them to be reassured that the government is looking very carefully at this."

He had discussed the issue recently with other leaders, at the G7 summit of leading industrialised nations, Mr Sunak said, and would raise it again in the US soon.

The G7 has recently created a working group on AI.
