Artificial intelligence poses a similar risk of human extinction as pandemics and nuclear war, experts have warned.

The boss of the firm behind ChatGPT, the head of Google’s AI lab, and CEO of Anthropic – another major AI firm, have all signed an open letter.

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

The Center for AI Safety, which published the statement, said it hoped to open up the discussion as “it can be difficult to voice concerns about some of advanced AI’s most severe risks”.

Dan Hendrycks, the director of the Center for AI Safety, told Sky News: “Humans have been the dominant species on Earth because of our intelligence. But now, as AI is becoming more powerful and more intelligent, we won’t occupy that same position in the future.

‘AI could put us in a fragile position’

“That could put us in a more fragile position and we could possibly go the way of the Neanderthals or the gorillas.”

British computer scientist Geoffrey Hinton and Yoshua Bengio, considered by many to be the “godfathers” of AI, have also put their names to the warning.

More than 350 people working in the field as engineers, researchers or executives have signed up.

AI’s rapidly growing capabilities have prompted similar concern from other high-profile figures in recent months – although not everyone in the industry believes it poses an existential threat.

AI is getting ‘crazier and crazier’

And Elon Musk joined a group of experts in March to call for a six-month pause in the training of large language AI models – the type used by ChatGPT and similar chatbots.

That letter warned of “profound risks” and said powerful systems should only be developed when it could be assured “their effects will be positive and their risks will be manageable”.

The spread of disinformation, the loss of millions of jobs, through to existential threats to the human race are often cited as potential dangers if AI continues to evolve rapidly.

Prime Minister Rishi Sunak has met the heads of leading AI companies, as well as Google boss Sundar Pichai, about the need to regulate the technology and mitigate risks.

Though still in its infancy, the technology has already received attention for its ability to produce convincing fake images and video, as well as cloned music tracks.

The popularity of ChatGPT is also said to have left teachers “bewildered” as they struggle to assess the benefits and risks to the education system.

Last week, ChatGPT’s capability grew again when it gained access to real-time search data, meaning it can give answers based on up-to-date news and current affairs.

Post Office inquiry: Former complaints handler executive says she never ‘knowingly’ did anything wrong

Post Office inquiry: Former complaints handler executive says she never 'knowingly' did anything wrong

A former top Post Office executive has told the Horizon scandal inquiry she never “knowingly” did anything wrong and did not remember a 2010 email saying that cash balances in sub-postmasters’ branch accounts could be remotely accessed.

Angela van den Bogerd, who held various roles over 35 years at the organisation, made the comments after opening her evidence on Thursday by saying she was “truly, truly sorry” for the “devastation” caused to wrongly convicted sub-postmasters.

Her roles at the Post Office included handling complaints about its Horizon software, which was provided by Japanese firm Fujitsu.

More than 700 Post Office managers were prosecuted between 1999 and 2015, after the system made it seem like money was missing from branches. At the time, the company insisted Horizon was robust.

Ms van der Bogerd, who was played by Coronation Street actress Katherine Kelly in the ITV drama Mr Bates Vs The Post Office, had previously not spoken publicly since a 2019 High Court case.

At the time, Judge Peter Fraser criticised her testimony and said she “did not give me frank evidence, and sought to obfuscate matters, and mislead me”.

Jason Beer KC, lead counsel to the inquiry, challenged Ms van den Bogerd’s opening statement, as he accused her of not saying sorry for her own role in the scandal.

Ms van den Bogerd, who resigned as the Post Office’s business improvement director in 2020, said she regretted missing significant documents and apologised for “not getting to the answer more quickly”.

She said: “But with the evidence I had and the parameters of my role at the time, I did the best I could to the best of my ability.”

Ms van den Bogerd added: “I didn’t knowingly do anything wrong and I would never knowingly do anything wrong.”

The inquiry heard that Ms van den Bogerd was sent an email in December 2010 informing her Fujitsu could remotely amend cash balances in branch accounts via Horizon.

She told the inquiry she had no memory of it and only became aware of the issue in a January 2011 email.

The inquiry was shown a transcript of a meeting that same month between her and sub-postmistress Rachpal Athwal, who was sacked after being wrongly accused of stealing £710 before being reinstated.

In the meeting, Ms van den Bogerd said Horizon could not be accessed remotely by anyone from the Post Office, without mentioning that Fujitsu could, the inquiry heard.

Mr Beer asked: “Are you saying that what you said overall there is accurate?”

Ms van den Bogerd replied: “So that is accurate. I go on to talk later about Fujitsu, I believe”. Mr Beer said it was inaccurate because she had not given the full picture.

Scandal ‘tip of the iceberg’

The inquiry also heard that, prior to a High Court case in 2019, Ms van den Bogerd made a witness statement in 2018 in which she said the first she knew of the possibility of inserting transactions into the system remotely was in the year or so before.

Mr Beer told the inquiry: “That was false.”

She replied: “Well, at the time I didn’t think it was.”

Pressed further on the issue, she said the messaging on remote access was “constantly changing” and that colleagues had been “very strong” that such access was “impossible”.

‘I have had breakdowns’

Ms van den Bogerd was also asked about an October 2014 email she and other senior staff were sent by Post Office media officer Melanie Corfield, which discussed what the response should be if anyone asked about remote access to Horizon.

The email said: “Our current line if we are asked about remote access potentially being used to change branch data/transactions is simply: ‘This is not and never has been possible’.”

Mr Beer said: “You knew that was false from multiple sources by then, by now, didn’t you?”

Ms van den Bogerd appeared flustered, before replying: “Clearly I was aware of that and just didn’t pick this up… it didn’t register with me at the time, but obviously from what we’ve discussed then this was incorrect terms of reference of a flow of information, yes.”

She added she was “certainly not trying to cover up… it wasn’t just me, there were other people party to the same information”.

Meanwhile, earlier in the hearing, the former executive said she agreed with Mr Beer that using words such as “exception” or “anomaly” to describe computer bugs had been an “attempt to control the narrative”.

The inquiry continues.

Unions vow to fight ‘rejection’ of plan to save Tata Steel jobs

Unions vow to fight 'rejection' of plan to save Tata Steel jobs

Unions have warned of a bitter fight ahead, saying their plans to avert thousands of job losses at Tata Steel have been rejected by the company.

Tata had announced in January a consultation on cutting up to 2,800 jobs in the UK, the majority of them at the country’s biggest steelworks in Port Talbot, South Wales.

It followed confirmation that the Indian-owned firm wanted to close down the blast furnaces at the plant and replace them with electric arc furnaces under a plan to reduce emissions and costs.

GMB, Unite and Community union representatives met Tata counterparts at a London hotel to discuss the way forward on Thursday morning.

But the GMB said Tata informed them that the blast furnaces would be closed by the end of September, describing the decision as an “unwelcome but not expected slap in the face”.

Tata Steel was yet to comment.

It has consistently argued that its £1.25bn investment would secure the future of UK steelmaking.

“It would protect the majority of jobs, reduce the UK’s carbon emissions by five million tonnes a year and could kickstart a green industrial revolution in South Wales,” a spokesperson said.

However, its operations are now widely expected to face strike action.

Members of Community and the GMB are being balloted on whether to walk out over the plans.

Unite members have already voted in favour of industrial action.

Why is green steel such a big issue?

The unions had urged Tata to abandon the government-supported switch to so-called green steel by signing up to an alternative plan that would raise productivity and protect jobs across the supply chain.

They argued that Tat’s proposals would rid the UK economy of its last remaining ‘virgin’ steelmaking facility and commit thousands of jobs to the scrap heap for no reason.

Community general secretary Roy Rickhuss said: “It’s incredibly disappointing that Tata have chosen to reject the multi-union plan, which is an ambitious and viable alternative to their destructive bad deal for steel.

Port Talbot: Community ‘smashed to pieces’

“We do not accept the company’s assertion our plan was too expensive – in fact, it would have returned the company to profits, and the additional capital expenditure needed to make it a reality could have been funded by an additional £450m from the government – a drop in the water compared to what other European countries are investing in their domestic steel industries.

“Tata have made their decision, and our members will decide on our collective response.

“Tata made a proposal to negotiate a package with the unions to give us firm assurances on jobs and future investment, and we will consult our members on how we proceed

“We want to make one thing absolutely clear to the company: this isn’t over – not by a long shot. We will never stop fighting for our jobs, our industry, and our proud steel communities.”
