A man tells his wife about his AI lover. A teenager dies after messaging his AI girlfriend. A marriage collapses after advice from an AI therapist. In this six-part narrative series, FT tech reporter Cristina Criddle explores the increasingly prominent role AI chatbots are playing in our emotional lives - and how artificial intelligence is reshaping intimacy. Can we trust AI with our most vulnerable selves? And what happens when th...

How will Silicon Valley’s most powerful figures shape technology — and politics — in 2026? Last year, Elon Musk and Mark Zuckerberg aligned themselves with Donald Trump. Where have these relationships left the industry today? The push to break up Big Tech appears to be fading, but the race for AI dominance has sparked new risks and rivalries, as well as regulatory flashpoints.

In this episode of Tech Tonic, Murad Ahmed...

Gene and stem cell therapies have been touted as the next phase in the longevity movement, with promises to rejuvenate the body at the cellular level and reverse the effects of ageing. But, as the prospect of life extension moves into the mainstream, it presents big questions for society as a whole. Are we ready for a world where people live much longer lives?

In this final episode, the FT’s Michael Peel and Hannah Kuchler dive ...

Singapore has become a model for longevity-focused healthcare. With an ageing population and citizens willing to spend money on anti-ageing treatments, the government and private companies are spending big on new ways to slow ageing, and help people live healthier for longer.

In this episode the FT’s Michael Peel visits the city-state to find out how longevity treatments are moving into the mainstream. He meets venture capitalis...

How much do we really know about ageing? For decades, scientists have been trying to understand the biology of the ageing process - what happens to our bodies as we get older? And is it possible to slow that process down or even stop it all together?

In this series of Tech Tonic, the FT’s Hannah Kuchler and Michael Peel look into the past, present and future of longevity - the wellness movement focused on extending and bettering...

Investors are spending billions of dollars on novel ways to extend human life through inventive treatments, therapies, and even manipulating our genes. And increasingly, it seems as though anti-ageing efforts have moved from the super rich to a mass market consumer industry. In this series, we’re covering the past, present and future of the longevity movement. We’ll be looking at where the fixation on longevity is coming from, and ...

For decades, science fiction writers have envisaged colonising Mars, even building cities on the red planet. Advocates for Mars exploration, such as Elon Musk, want to make that vision a reality. But can humans really live in an alien world? 

The FT’s space industry editor Peggy Hollinger speaks to researchers about the physical and mental pressures astronauts would face living millions of miles from home and to scientists ...

US President Donald Trump wants to “plant the stars and stripes on the planet Mars”. But more than 50 years on from the moon landings, America’s space agency, Nasa, is in disarray. Meanwhile, China is forging ahead with its own plans for manned missions to the Moon and perhaps to Mars. Who will win the race to the red planet? 

The FT’s space industry editor Peggy Hollinger speaks to former and current Nasa employees ab...

Elon Musk wants humans to settle on Mars, and his rocket company SpaceX is spending billions of dollars on developing the spacecraft to take us there. The ‘Starship’ is being designed to take astronauts back to the moon, and eventually, on to the red planet. But why is Musk so obsessed with building a colony on Mars, and is he really the man to take us there? 

The FT’s space industry editor Peggy Hollinger speaks to space e...

US President Donald Trump has pledged to “plant the stars and stripes on the planet Mars”, China could send its first crewed mission to Mars within a decade, and Elon Musk wants people to actually settle on Mars, transforming the human race into an interplanetary species. 

In a new series of Tech Tonic, the FT’s Peggy Hollinger asks if we’re really about to land, and even live, on the red planet.

AI models have learned to create their own music by harvesting millions of songs from the internet. But critics say they’re using musicians’ work without permission, and three major record labels are suing them for ‘copyright infringement on an almost unimaginable scale’. 

In the second episode of this two part series, the FT’s pop critic Ludovic Hunter-Tilney speaks to campaigners and lawyers about the legal battle over AI...

Generative AI models trained on vast swaths of popular music can create songs almost indistinguishable from human-made work. For some, they represent the future of pop music. For others, they threaten to flood the world with ‘AI slop’, drowning out the work of human artists, stealing musicians' jobs, and ending the process of music-making as we know it. Is this just a case of technophobia? Or could AI music generators replace human...

AI music generators - platforms that use artificial intelligence to create new, original music from scratch - can make songs that are almost indistinguishable from human creations. For some musicians, they’re the next frontier in music-making technology. But for others, they represent a grave threat, flooding the world with low-grade AI music, stealing the jobs of working musicians, and even spelling the end of the creative process...

Peter Thiel is unlike any other Trump tech bro. As well as a wildly successful investor, he’s seen as a thinker - the philosopher king of Silicon Valley. Thiel’s acolytes in the tech world and Washington include vice-president JD Vance but his relationship with the Trump camp is complicated. And there are still questions about what, if anything, he wants with the president.

In the final episode of this season of Tech Tonic, Mura...

Meta chief executive Mark Zuckerberg has undergone a transformation, both physical and political. The skinny teenager who founded Facebook in his dorm room is now a muscular jiu-jitsu enthusiast who’s called US President Donald Trump a “badass” and wants to see more “masculine energy” in the workplace. 

Is this all an act? Is Zuckerberg doing whatever it takes to ingratiate himself with the Trump administration and ensure t...
