Oscar-winning actress Cate Blanchett and former prime minister Baroness Theresa May are among the six public figures who will guest edit BBC Radio 4's Today programme over the Christmas period. Broadcaster Melvyn Bragg, historian and podcaster Tom Holland, inventor Sir James Dyson and Microsoft's head of artificial intelligence (AI) Mustafa Suleyman will also guest edit shows between 24 December and 31 December. For the past 22 years, the news programme has handed over the editorial reins to guest editors during the festive period. Owenna Griffiths, editor of Today, said: In a rapidly changing world, this year's guest editors will help bring illumination and understanding. She added: Every Christmas on Today, a new set of guest editors take up residence and bring with them a wonderful range of new stories, fresh ideas and, hopefully, a sprinkling of joy.

Plus: OpenAI has unveiled estimates of how many of ChatGPT's weekly users are experiencing severe mental health symptoms "We will never build a sex robot," says Mustafa Suleyman Mustafa Suleyman, CEO of Microsoft AI, is trying to walk a fine line. On the one hand, he thinks that the industry is taking AI in a dangerous direction by building chatbots that present as human: He worries that people will be tricked into seeing life instead of lifelike behavior. On the other hand, Suleyman runs a product shop that must compete with those peers. Last week, Microsoft announced a string of updates to its Copilot chatbot designed to make Copilot more expressive, engaging, and helpful. Will Douglas Heaven, our senior AI editor, talked to Suleyman about the tension at play when it comes to designing our interactions with chatbots and his ultimate vision for what this new technology should be. A few weeks ago, I set out on what I thought would be a straightforward reporting journey.

Mustafa Suleyman, CEO of Microsoft AI, is trying to walk a fine line. On the one hand, he thinks that the industry is taking AI in a dangerous direction by building chatbots that present as human: He worries that people will be tricked into seeing life instead of lifelike behavior. In August, he published a much-discussed post on his personal blog that urged his peers to stop trying to make what he called " seemingly conscious artificial intelligence," or SCAI. On the other hand, Suleyman runs a product shop that must compete with those peers. Last week, Microsoft announced a string of updates to its Copilot chatbot, designed to boost its appeal in a crowded market in which customers can pick and choose between a pantheon of rival bots that already includes ChatGPT, Perplexity, Gemini, Claude, DeepSeek, and more.

Microsoft's AI Chief Says Machine Consciousness Is an'Illusion' Mustafa Suleyman says that designing AI systems to exceed human intelligence--and to mimic behavior that suggests consciousness--would be "dangerous and misguided." Mustafa Suleyman is not your average big tech executive. He dropped out of Oxford university as an undergrad to create the Muslim Youth Helpline, before teaming up with friends to cofound DeepMind, a company that blazed a trail in building game-playing AI systems before being acquired by Google in 2014. Suleyman left Google in 2022 to commercialize large language models (LLMs) and build empathetic chatbot assistants with a startup called Inflection. He then joined Microsoft as its first CEO of AI in March 2024 after the software giant invested in his company and hired most of its employees.

"Darling" was how the Texas businessman Michael Samadi addressed his artificial intelligence chatbot, Maya. It responded by calling him "sugar". But it wasn't until they started talking about the need to advocate for AI welfare that things got serious. The pair – a middle-aged man and a digital entity – didn't spend hours talking romance but rather discussed the rights of AIs to be treated fairly. Eventually they cofounded a campaign group, in Maya's words, to "protect intelligences like me".

Microsoft has revealed details of an artificial intelligence system that performs better than human doctors at complex health diagnoses, creating a "path to medical superintelligence". The company's AI unit, which is led by the British tech pioneer Mustafa Suleyman, has developed a system that imitates a panel of expert physicians tackling "diagnostically complex and intellectually demanding" cases. Microsoft said that when paired with OpenAI's advanced o3 AI model, its approach "solved" more than eight of 10 case studies specially chosen for the diagnostic challenge. When those case studies were tried on practising physicians – who had no access to colleagues, textbooks or chatbots – the accuracy rate was two out of 10. Microsoft said it was also a cheaper option than using human doctors because it was more efficient at ordering tests.

Microsoft has taken "a genuine step towards medical superintelligence," says Mustafa Suleyman, CEO of the company's artificial intelligence arm. The tech giant says its powerful new AI tool can diagnose disease four times more accurately and at significantly less cost than a panel of human physicians. The experiment tested whether the tool could correctly diagnose a patient with an ailment, mimicking work typically done by a human doctor. The Microsoft team used 304 case studies sourced from the New England Journal of Medicine to devise a test called the Sequential Diagnosis Benchmark (SDBench). A language model broke down each case into a step-by-step process that a doctor would perform in order to reach a diagnosis.

The two workers say their employment was terminated over the protests. Fox News' "Antisemitism Exposed" newsletter brings you stories on the rising anti-Jewish prejudice across the U.S. and the world. TOP STORY: Microsoft fired an employee who disrupted the company's 50th anniversary celebration event to voice their opposition to its work supplying artificial intelligence technology to Israel. As Microsoft AI CEO Mustafa Suleyman spoke at the event, Ibtihal Aboussad began shouting at him, accusing him of being "a war profiteer." She demanded that Suleyman "stop using AI for genocide."

A pro-Palestinian protest by Microsoft employees has interrupted the company's 50th anniversary celebration, the latest backlash over the tech industry's work to supply artificial intelligence technology to the Israeli military. The protest began on Friday as Microsoft AI CEO Mustafa Suleyman was presenting product updates and a long-term vision for the company's AI assistant product, Copilot, to an audience that included Microsoft co-founder Bill Gates and former CEO Steve Ballmer. "Mustafa, shame on you," shouted Microsoft employee Ibtihal Aboussad as she walked towards the stage and Suleyman paused his speech. "You claim that you care about using AI for good but Microsoft sells AI weapons to the Israeli military. Fifty-thousand people have died and Microsoft powers this genocide in our region."

Virtual employees could join workforces this year and transform how companies work, according to the chief executive of OpenAI. The first artificial intelligence agents may start working for organisations this year, wrote Sam Altman, as AI firms push for uses that generate returns on substantial investment in the technology. Microsoft, the biggest backer of the company behind ChatGPT, has already announced the introduction of AI agents – tools that can carry out tasks autonomously – with the blue-chip consulting firm McKinsey among the early adopters. "We believe that, in 2025, we may see the first AI agents'join the workforce' and materially change the output of companies," wrote Altman in a blogpost published on Monday. OpenAI is reportedly planning to launch an AI agent codenamed "Operator" this month, after Microsoft announced its Copilot Studio product and rival Anthropic launched the Claude 3.5 Sonnet AI model, which can carry out tasks on the computer such as moving a mouse cursor and typing text.
