What was really behind Jack Dorsey laying off nearly half of Block’s staff?

Jack Dorsey cited AI as the driving force behind cutting 40% of his company’s employees, but other factors such as a weak crypto market, overstaffing and a declining stock price may also have motivated the move.Last week, the financial technology company Block announced that it would lay off 4,000 of its 10,000 workers. Dorsey, Block’s CEO, said in a letter to shareholders that advances in AI “have changed what it means to build and run a company”.“We’re already seeing it internally. A significantly smaller team, using the tools we’re building, can do more and do it better

OpenAI amends Pentagon deal as Sam Altman admits it looks ‘sloppy’

OpenAI is amending its hastily arranged deal to supply artificial intelligence to the US Department of War (DoW) after the ChatGPT owner’s chief executive admitted it looked “opportunistic and sloppy”.The contract prompted fears the San Francisco startup’s AI could be used for domestic mass surveillance but its boss, Sam Altman, said on Monday night the startup would explicitly bar its technology from being used for that purpose or being deployed by defence department intelligence agencies such as the National Security Agency (NSA).OpenAI, which has more than 900 million users of ChatGPT, made the deal almost immediately after the Pentagon’s existing AI contractor, Anthropic, was dropped.Anthropic had insisted “using these systems for mass domestic surveillance is incompatible with democratic values”, leading the US president, Donald Trump, to call Anthropic “leftwing nut jobs” and directing the federal government to stop using its technology.Despite denials from OpenAI that the agreement allowed for surveillance use, commentators raised the spectre of the Snowden scandal, which broke in 2013, when it emerged the NSA was engaged in mass harvesting of phone and internet communications

Iran war heralds era of AI-powered bombing quicker than ‘speed of thought’

The use of AI tools to enable attacks on Iran heralds a new era of bombing quicker than “the speed of thought”, experts have said, amid fears human ­decision-makers could be sidelined.Anthropic’s AI model, Claude, was reportedly used by the US military in the barrage of strikes as the technology “shortens the kill chain” – meaning the process of target identification through to legal approval and strike launch.The US and Israel, which previously used AI to identify targets in Gaza, launched almost 900 strikes on Iranian targets in the first 12 hours alone, during which Israeli missiles killed Iran’s supreme leader, Ayatollah Ali Khamenei.Academics studying the field say AI is collapsing the planning time required for complex strikes – a phenomenon known as “decision compression”, which some fear could result in human military and legal experts merely rubber-stamping automated strike plans.In 2024 the San Francisco-based Anthropic deployed its model across the US Department of War and other national security agencies to speed up war planning

Anthropic’s AI model Claude gets popularity boost after US military feud

The AI model Claude has surged in popularity after being blacklisted by the Pentagon last week over ethics concerns.Claude climbed to the No 1 spot on Apple’s chart of top free apps on Saturday in the US – dethroning OpenAI’s ChatGPT, just one day after the Pentagon tapped OpenAI to supply AI to classified military networks. The bot’s app climbed the iPhone app charts in the UK but did not beat out ChatGPT. Claude also raced up the Android charts in the US and UK, though ChatGPT reigned supreme, according to data from Sensor Tower.Claude and other apps by the startup Anthropic suffered outages early Monday amid what the company described as “unprecedented demand for Claude” over the last week

UK firms in Middle East face heightened threat from Iran hackers, agency warns

UK businesses with a presence in the Middle East have been urged to step up vigilance against cyber threats from Iran after US-Israeli attacks.The National Cyber Security Centre (NCSC) said there was “almost certainly” a heightened risk of an indirect cyber threat for organisations that had offices, or supply chains, in the Middle East.The UK’s cybersecurity agency said Iran remained a threat despite an extensive bombing campaign that has devastated the country’s political and military leadership, including the death of its supreme leader, Ayatollah Ali Khamenei.“Iranian state and Iran-linked cyber actors almost certainly currently maintain at least some capability to conduct cyber activity,” said the NCSC.The agency said in an alert published on Monday that there was “likely” no significant change in the direct cyber threat from Iran to the UK, but organisations should prepare for the risk of collateral damage from Iran-linked hacktivists

US military reportedly used Claude in Iran strikes despite Trump’s ban

The US military reportedly used Claude, Anthropic’s AI model, to inform its attack on Iran despite Donald Trump’s decision, announced hours earlier, to sever all ties with the company and its artificial intelligence tools.The use of Claude during the massive joint US-Israel bombardment of Iran that began on Saturday was reported by the Wall Street Journal and Axios. It underlines the complexity of the US military withdrawing powerful AI tools from its missions when the technology is already intricately embedded in operations.According to the Journal, US military command used the tools for intelligence purposes, as well as to help select targets and carry out battlefield simulations.On Friday, just hours before the Iran attack began, Trump ordered all federal agencies to stop using Claude immediately
