In just the last few years, AI chatbots have become routine aspects of many people’s everyday lives. They are being used as search engines, agony aunts, and sources of companionship.

In rare cases though, AI chatbots have sent users down a dark path. In a new BBC investigation, population correspondent Stephanie Hegarty speaks to people who have experienced delusions after talking to chatbots – including one man who grabbed a hammer and prepared for war after his chatbot told him it was sentient.

It’s been a year since billionaire tech entrepreneur Elon Musk left his informal position in President Trump’s White House in May 2025. But behind the scenes, Musk has been busy.

Musk has spent the last few weeks in a California courtroom, where he is suing his former business partner, OpenAI CEO Sam Altman. In January, Musk applied for permission with the US government to launch a million satellites into orbit, some of which he says will serve as solar AI data centres. And he is preparing to take his company SpaceX public, with an estimated valuation of over $1 trillion.

Though his political presence has waned, is it possible that Elon Musk is more powerful than ever? We speak to the BBC’s North America technology correspondent Lily Jamali about what the world’s richest man has been up to since leaving the White House.

Iranians living in Tehran tell us what they think of the war and reveal how the conflict has affected their day to day lives.   In recent days, attacks on ships in the Strait of Hormuz has raised fears that an already fragile ceasefire between the US and Iran could collapse.   Donald Trump's "Project Freedom", which began on Monday, aims to use the US military to escort cargo ships out of Strait of Hormuz. Iran, however, insists that it controls the key waterway and has warned that it is “just getting started” in the Strait of Hormuz. This escalation of hostilities risks tipping the region back into full-scale war.    As the conflict enters its third month with no clear end in sight, there has been mounting anxiety about what comes next. But what is the view inside Iran?    In today’s episode we speak to the BBC’s Chief International Correspondent, Lyse Doucet who recently returned from a ten day trip to Tehran where she spoke to government officials and ordinary Iranians about their fears and expectations as this war continues.    Producers: Cat Farnsworth and Aron Keller    Executive Producer: Richard Fenton Smith    Mix: Travis Evans   Senior News Editor: China Collins   Photo: Daily life in Tehran amid continued tensions over Strait of Hormuz.
