The future is coming at Croydon fast. It might not look like Britain's cutting edge but North End, a pedestrianised high street lined with the usual mix of pawn shops, fast-food outlets and branded clothing stores, is expected to be one of two roads to host the UK's first fixed facial recognition cameras. Digital photographs of passersby will be silently taken and processed to extract the measurements of facial features, known as biometric data. They will be immediately compared by artificial intelligence to images on a watchlist. Alerts can lead to arrests.

Police believe live facial recognition cameras may become "commonplace" in England and Wales, according to internal documents, with the number of faces scanned having doubled to nearly 5m in the last year. A joint investigation by the Guardian and Liberty Investigates highlights the speed at which the technology is becoming a staple of British policing. Major funding is being allocated and hardware bought, while the British state is also looking to enable police forces to more easily access the full spread of its image stores, including passport and immigration databases, for retrospective facial recognition searches. Live facial recognition involves the matching of faces caught on surveillance camera footage against a police watchlist in real time, in what campaigners liken to the continual finger printing of members of the public as they go about their daily lives. Retrospective facial recognition software is used by the police to match images on databases with those caught on CCTV and other systems.

In less than a year-and-a-half, Frankie Johnson, a man incarcerated at the William E Donaldson prison outside Birmingham, Alabama, says he was stabbed around 20 times. In December of 2019, Johnson says, he was stabbed "at least nine times" in his housing unit. In March of 2020, an officer handcuffed him to a desk following a group therapy meeting, and left the unit, after which another prisoner came in and stabbed him five times. In November of the same year, Johnson says, he was handcuffed by an officer and brought to the prison yard, where another prisoner attacked him with an ice pick, stabbing him "five to six times", as two correctional officers looked on. According to Johnson, one of the officers had actually encouraged his attacker to carry out the assault in retaliation for a previous argument between Johnson and the officer.

She needs to be spoken to slowly and clearly, as you'd talk to an aged relative with diminished faculties. '"Alexa, how long do wasps live for?" "Alexa, how long do wasps live if you hit them with a tea towel and then a saucepan?" In September 2016, a new presence appears in our house, squatting on the kitchen counter between the kettle and the coffee machine. It is blandly futuristic, a minimal cylinder with an LED ring that glows blue to alert us to the fact that it is ready, poised to answer our questions or carry out our instructions, as long as those instructions are clearly stated and fall within a narrow band of available "skills".

But opting out is impossible to do without AI transparency. The plan is a charter for theft, since creatives would have no idea who is taking what, when and from whom. When the government stoops to a preferred outcome that undermines the moral right to your work and income, you might reasonably be angered. As Elton John said last weekend: "The government have no right to do this to my songs. They have no right to do it to anybody's songs, or anybody's prose."

This year's surprise hit Blue Prince is a proper video game wonder. It's an architectural puzzler in which you explore a transforming mansion left to you by an eccentric relative. The place is filled with secrets, and whenever you reach a door you get to pick the room on the other side from a handful of options. The whole game is a rumination on houses and how we live in them. Nostalgic and melancholic, it feels designed to make us look harder at what surrounds us. This Addams'-style Queen Anne with clapboard facades and dark windows is a classic haunted house, reportedly inspired by the Skywalker Ranch.

Everything over the last 30 years, according to Sir Jony Ive, has led to this moment: a partnership between the iPhone designer and the developer of ChatGPT. Ive has sold his hardware startup, io, to OpenAI and will take on creative and design leadership across the merged businesses. "I have a growing sense that everything I have learned over the last 30 years has led me to this place, to this moment," he says in a video announcing the 6.4bn ( 4.8bn) deal. The main aim will be to move on from Ive's signature achievement designing Apple's most successful product, as well as the iPod, iPad and Apple Watch. The British-born designer has already developed a prototype io device, and one of its users is OpenAI's chief executive, Sam Altman.

Artificial intelligence systems could account for nearly half of datacentre power consumption by the end of this year, analysis has revealed. The estimates by Alex de Vries-Gao, the founder of the Digiconomist tech sustainability website, came as the International Energy Agency forecast that AI would require almost as much energy by the end of this decade as Japan uses today. De Vries-Gao's calculations, to be published in the sustainable energy journal Joule, are based on the power consumed by chips made by Nvidia and Advanced Micro Devices that are used to train and operate AI models. The paper also takes into account the energy consumption of chips used by other companies, such as Broadcom. The IEA estimates that all data centres – excluding mining for cryptocurrencies – consumed 415 terawatt hours (TWh) of electricity last year.

The Cannes film festival isn't typically associated with video games, but this year it's playing host to an unusual collaboration. Lili is a co-production between the New York-based game studio iNK Stories (creator of 1979 Revolution: Black Friday, about a photojournalist in Iran) and the Royal Shakespeare Company, and it's been turning heads with its eye-catching translocation of Macbeth to modern-day Iran. "It's been such an incredible coup to have it as the first video game experience at Cannes," says iNK Stories co-founder Vassiliki Khonsari. "People have gone in saying, I'm not familiar playing games, so I may just try it out for five minutes. The Cannes festival's Immersive Competition began in 2024, although the lineup doesn't usually feature traditional video games. "VR films and projection mapping is the thrust of it," says iNK Stories' other co-founder, Vassiliki's husband Navid Khonsari. But Lili weaves live-action footage with video game mechanics in a similar way to a game such as Telling Lies or Immortality. Its lead, Zar Amir Ebrahimi, won best actress at Cannes three years ago. Lili focuses on the story of Lady Macbeth, here cast as the ambitious wife of an upwardly mobile officer in the Basij (a paramilitary volunteer militia within the Islamic Revolutionary Guard in Iran). As in the play, she plots a murder to secure her husband's rise. "I think that the narrative of Lady Macbeth is that she's manipulative, and that's exactly what got us interested," says Navid. "The social limitations based on her gender forced her to try to attain whatever leadership role she can," he continues. "If she was a man, she would have been one of the greatest kings that country would have ever experienced, but because she was a woman she had to work within the structure that was there for her.

OpenAI is buying an untested startup for 6.4bn, the ChatGPT maker's biggest acquisition yet. The hardware startup, called io, was founded by Apple design guru Jony Ive, known best as one of the principal architects of the iPhone. Ive and OpenAI's CEO, Sam Altman, said in a blog post that their partnership has been two years in the making. "A collaboration built upon friendship, curiosity and shared values quickly grew in ambition," they wrote in the blog post, which offered scant details on upcoming devices. "Tentative ideas and explorations evolved into tangible designs."
