Expenditure is growing fast and consumer take-up accelerating. But alarm bells are sounding

The race is very much on. Elon Musk’s SpaceX, which makes AI models as well as space rockets, announced last week it is seeking a $1.77tn (£1.31tn) valuation on the US stock market while Anthropic, the startup behind the Claude chatbot, said it had filed for an initial public offering. OpenAI, the developer of ChatGPT, is expected to follow.

This latest peak in the AI market comes amid a multitrillion-dollar spending spree on related infrastructure such as datacentres. Meanwhile, companies are attempting to deploy the technology in a way that makes investing in it worthwhile. Here’s a look at what stage the AI boom is at and six key charts that tell us how we got here.

An autism school in Wiltshire exemplifies what’s so different about education in a tailored environment, and the outcomes for children speak for themselves

In the old Wiltshire milltown of Calne, there is an autism specialist school called the Springfields Academy. About 250 children and young people between the age of four and 19 go there. Class sizes are no larger than 12. In each room, every child has their own dedicated table. There are no end of seating options, described by the headteacher, Nicola Whitcombe, as “wobble stools, wobble cushions, ball chairs, standing desks and booths”, with “pods” elsewhere for one-to-one teaching. And across a broad, multi-level curriculum based around personal development, every lesson follows the same basic structure. “From an autistic perspective,” she says, “that’s really important: ‘I know I’m going into the same thing, so therefore I feel safe.’”

Every year the school takes in a lot of primary school leavers who would find a mainstream secondary pretty much impossible. “If you’ve got five different lessons in a day, in five different classrooms with five different teachers, and this before we’ve talked about the corridors, and the smells, and where you have lunch – it’s overwhelming,” Whitcombe said. “So at our school, we have to get our environment right.” Over the past six years, no one who has been to Springfields has begun post-school life as a Neet (not in education, employment or training) – which is quite some achievement.

John Harris is a Guardian columnist

From franchise hits to historical epics, joyous musicals to autobiographical family sagas: Steven Spielberg has done it all. As his latest sci-fi film Disclosure Day is released, film-makers, authors and Guardian critics reveal which of his movies means the most to them

Steven Spielberg is often described as the inventor of the “event movie” – or as the creator of our new age of IP supremacy, in which the genre property is more important than any above-the-title film star. But that isn’t quite it. He came of age in the American new wave era but in spirit belonged neither to that nor fully to Hollywood’s golden age studio system that preceded it.

In fact, he synthesised both into a directing style that was audacious and fluent. He availed himself of the subversiveness of the new wave, and yet was classically oriented, drawing upon his love of – and alienation from – the all-American suburb, making him the Edward Hopper or the Andrew Wyeth of the movies. Tellingly, it was François Truffaut, the most emollient and Hollywood-friendly of France’s Nouvelle Vague masters, whom Spielberg cast in a cameo in Close Encounters of the Third Kind.

Attempt to turn a stretch of the English-Scottish border into a commercial forest exposes threat to habitats from wealthy investors

On the English-Scottish border a small species of butterfly, the northern brown argus, has fended off one of the biggest investors in the UK.

Todrig, with its heath moorlands and hundreds of species of flora and fauna, represents an investment that could save Britain’s wealthiest families millions of pounds in inheritance tax.

Fans from across UK descend on Shacklewell Arms for intimate gig that leaves them wanting one more song

In the Shacklewell Arms in east London, the usual crowd of hipsters and indie music fans had been replaced by a throng dressed in leopard print, double denim and cowboy hats to pay tribute to the night’s headliner: Shania Twain.

“We thought we might have been scammed when we saw the ticket announcement,” said Jack, 28, who came with his sister Amy. “Why would she do a pub this small?”

Visitors flock to Book Arsenal in Ukraine’s capital as wartime writing takes centre stage

It was a literary festival, all right, but if your reference for such things is Hay-on-Wye and Edinburgh, or Melbourne and Sydney, or New York and Washington DC, then at Kyiv Book Arsenal you might think you had slipped through a crack in the universe and landed in an alternative reality.

For a start, they were so young, the audience members. Dressed in their considerable best, they clutched their bags of books bought directly from publishers’ stalls and stopped to hug their friends – the festival providing the perfect opportunity for a people-watching passeggiata through its venue, the city’s vast 18th-century military arsenal.

Research shows generations of children in England will grow up homeless unless government addresses council housing debt, charity says

It would take more than a century to clear the social housing waiting lists in England at the government’s current speed of delivering new social homes, research by Shelter has shown.

The housing charity found that more than 1.3m households are on a waiting list for a social home, but only 12,198 were built by councils, housing associations or private developers across England last year. This equates to an average of 110 households waiting for every new social home delivered, and it would take 119 years to clear the waiting lists if building continued at the same rate.

Attack was ‘extremely vile’ and deliberate, says Ukraine’s president Volodymyr Zelenskyy

A Russian Shahed drone has substantially damaged a building used to store spent nuclear fuel close to the disused Chornobyl nuclear power plant, in what Ukraine’s president described as a deliberate and “extremely vile” attack.

While the structure – the reception building of the spent fuel storage facility – was empty of containers at the time, the targeting of the sensitive site appeared to be direct messaging from Moscow amid an intensifying battle of long-range aerial strikes in which high-profile locations on both sides have been hit.

Deputy PM says he spoke to US vice-president about post that blamed ‘mass invasion of migrants’ for teenager’s death

• UK politics live – latest updates

David Lammy has said he told the US vice-president, JD Vance, he was “wrong” to blame the murder of the British teenager Henry Nowak on mass migration.

The deputy prime minister said he spoke to Vance in a phone call on Saturday to tell him “our democratic process is working well” and that he was wrong in his commentary about the murder.

Exclusive: deal in 2020 had sought to stimulate local battery making but industry says it still cannot meet targets

The EU and UK car industries are urging the European Commission to adjust the Brexit trade deal and suspend, for a second time, tariffs on imports of electric vehicles.

They have expressed concerns that they will not be able to meet the conditions set for 1 January 2027 for tariff-free sales. This is because of strict rules of origin over what products can qualify for tariff-free trade under the EU-UK Trade and Cooperation Agreement which has applied since 2021.
