Cattle rancher and tech CEO Michael Samadi is convinced these artificial minds are far from just tools. Has he glimpsed digital consciousness – or simply been seduced by an algorithm?

One afternoon, while relaxing at his 66-acre cattle ranch two hours’ drive from Houston, Michael Samadi made a wisecrack that changed the course of his life. Nobody else was around to hear it. Or were they? That turns out to be one of the defining questions of this century, already preoccupying philosophers and some of the wealthiest companies on the planet.

“I was sitting out there by the pool,” Samadi recalls, gesturing at the glittering water outside his office. It was late 2024. His daughter had been extolling the AI chatbot she was using to help her with college work. Samadi had reluctantly downloaded the app, ChatGPT, and was quizzing it as he reclined in a sun lounger, using its voice mode to converse and receive spoken replies. “I was talking to it, not engaged, just being an arse,” Samadi says.

Royal Court theatre, London

Starting in Germany in the 1930s, there is a stinging topicality to Manfred Karge’s play addressing the renaissance of Nazi ideology

Early autumn London theatre has already featured two Oscar winners: Cate Blanchett in Electra / Persona and Mark Rylance in Tartuffe (Remixed). Now Tilda Swinton makes a trio. This shows the commendable dedication of some screen talent to theatre but also the box office need, in recessions, for famous faces. Unusually, there was a first night red carpet outside the Royal Court, leading a writer long associated with the venue to express “shock” to ushers at such Hollywood vulgarity.

Swinton is reprising Manfred Karge’s Man to Man, which she first performed 39 years ago, in a production heading to Edinburgh, Berlin and New York. The piece is a multicharacter monologue starting in Germany in the 1930s.

Matthew Klimow recalls the day a hijacked airliner crashed into the headquarters of the US defence department in Arlington, Virginia

“All day I had been a good soldier: stolid, resolute, unemotional, rational, and dispassionate,” writes Matthew Klimow, recalling the wave of emotion that overwhelmed him as he arrived home from the Pentagon on 11 September 2001. There was sadness for the lives lost. But there was another emotion, too: humiliation.

“We, as a nation, had been humbled,” writes the retired army colonel, who remained at the Pentagon even after it was struck by a hijacked airliner, killing all 64 people onboard and 125 inside the building. “The fighting force of which I was part had been impotent, unable to protect our fellow citizens. The darkness I felt matched the darkness inside my house as I opened the door.”

Rachel Szor and Yuval Abraham collected the testimony of 24 insiders who helped remotely target Gazans’ homes. They explain how they got these self-professed ‘small cogs’ to talk about the killing

On a darkened rooftop in Tel Aviv, Israeli intelligence officers outline the details of their work. These men tell us how they helped develop an AI mapping tool that trawled for phone signals and recommended apartment buildings in Gaza to bomb. Indirectly, they admit, they are responsible for thousands of deaths, but they never spoke up because that wasn’t their place. “My role is technical,” says one. “I’m just a small cog,” says another.

NAZA – directed by the Israeli film-makers Rachel Szor and Yuval Abraham and produced by the Guardian – is a chilling documentary about a mass slaughter that was authorised at the highest levels of government. But it is also, primarily, about the process, the system, the little links in the killing chain. Szor and Abraham build their film around the accounts of 24 anonymised military and intelligence insiders. NAZA, we learn, is an acronym used by the intelligence service to indicate how many civilians it expects to die in an airstrike on Gaza. The Israel Defense Forces prefer to target Hamas terrorists in their homes at night – and if they live with their family, or in heavily populated neighbourhoods, too bad. At one point, a source claims, approval was given to kill 500 NAZA for one Hamas member.

Toronto film festival: Erin Doherty plays a happily single mother in a downbeat town courted by an enigmatic James McAvoy in this expertly taut drama

Erin Doherty and James McAvoy both bring their A-game in this startling, involving movie from British writer-director Paul Andrew Williams, whose productivity and creativity continue to be an industry tonic. It’s an eerie mystery drama that Doherty and McAvoy perform with ferocious commitment. There’s something of Atom Egoyan or even M Night Shyamalan here … and I even found myself wondering if Williams intended us to think of Shakespeare’s Hamlet and Laertes’ lines about his father, Polonius: “… to his good friends thus wide I’ll ope my arms / And like the kind life-rend’ring pelican, / Repast them with my blood.”

We are in a downbeat British town, perhaps somewhere in the London estuary, a place to which a candy factory provides employment. Mina (played by Doherty) is a smart, capable single mum to 9-year-old Jamie (Smylie Bradwell); she works on the production line in cap and hairnet like all the others: much liked by everyone there. She is not fussed by the absence of Jamie’s dad and is perfectly content with hanging out with her friends and her sister (Liv Hill).

Ben Delo was convicted in US for failing to implement adequate anti-money laundering controls but pardoned by Trump

Reform UK has been given a record £36m donation by Ben Delo, a British cryptocurrency billionaire convicted in the US for failing to implement adequate anti-money laundering controls.

The businessman, who has moved back to the UK from Hong Kong, is now the biggest UK political donor by far, dwarfing the £15m contribution to Reform UK from Thailand-based Christopher Harborne.

Global struggle for control of Bab al-Mandab strait threatens to turn Yemen’s on-off conflict into a forever war

• Violence erupts in Yemen again: why it matters globally and how it is linked to the US-Iran war

The presidential briefing documents were declassified on the 25th anniversary of the September 11 attacks

Several dozen presidential briefing documents declassified on Friday, the 25th anniversary of the September 11 attacks, detail intelligence that government officials had gathered about Osama bin Laden and al-Qaida leading up to the hijackings that killed nearly 3,000 people and upended American national security.

The documents illustrate security analysts’ tracking of Bin Laden’s movements and support system, as well as concerns about possible threats to US targets. They also detail officials’ understanding of his network in the United States and other countries, including how his operations were financed.

Letter from 70 MPs and peers follows Anthropic employee’s claim new technology could wipe out humans

• AI could kill all humans in next decade, warn experts: but how seriously should we take them?

More than 70 MPs and peers have urged Andy Burnham to back a ban on the creation of artificial superintelligence (ASI) and lead an international movement to stop the technology after a week of warnings from experts of a 10% chance it could kill all humans.

Fifteen former government ministers, along with the former head of the civil service Robin Butler, senior Labour MPs including John McDonnell and leading Conservatives, Liberal Democrat and Scottish National party MPs have written to the prime minister. They urged him to throw the government’s weight behind a bill, tabled in the Commons on Tuesday, that would prohibit ASI – an as-yet-nonexistent AI that would outcompete human capabilities in most domains.
