Who is Elon Musk? The pair discussed the potential benefits of AI, with Mr Musk saying: "One of my sons has trouble making friends and an AI friend would be great for him." There was also agreement on the possibilities AI presents for young people's learning, with Mr Musk saying it could be "the best and most patient tutor". ‘Like having a very smart friend’: Musk on impact of AI But there was a stark warning on the potentially ruinous impact it could have on traditional jobs. "We are seeing the most disruptive force in history here," Mr Musk said, before speculating: "There will come a point where no job is needed - you can have a job if you want one for personal satisfaction but AI will do everything. "It's both good and bad - one of the challenges in the future will be how do we find meaning in life." Reuters Amid all the philosophising, there was little in the way of new announcements about how the technology will be employed and regulated in the UK - aside from the prime minister's promise that AI could be used to improve the government's own website. Mr Musk was one of the star guests at this week's summit - but it briefly looked like the event with Mr Sunak might be a little overshadowed. Hours before it was due to begin, Mr Musk took to his own website X, formerly known as Twitter, to take a swipe at the summit. As Mr Sunak was on his feet giving his final press conference at Bletchley Park, Mr Musk shared a cartoon parodying an "AI Safety Summit". It depicted caricatures representing the UK, European Union, China and the US with speech bubbles reading "We declare that AI posses a potentially catastrophic risk to humankind" - while their thought bubbles read "And I cannot wait to develop it first". EPA-EFE-/REX/Shutterstock But in the end, the pair appeared at ease together, and Mr Sunak in particular looked in his element - perhaps even slightly bowled over by the controversial billionaire, who he called a "brilliant innovator and technologist". From the cheap seats behind the dignitaries of the tech world, it was hard to put your finger on who was really the powerful one out of this pair. Was it Mr Sunak as he asked the celeb tech billionaire questions? Or was it Mr Musk, who did much of the talking? Either way, both men hope to have a say in whatever our AI future has in store for us. Additional reporting by Tom Gerken and Shiona McCallum
