We handed kids the most powerful technology in history. Then we walked away. This is what happened next.

When she was 12 years old, Ava Smithing spiraled down a social media rabbit hole that nearly cost her life. A decade later, she discovered she wasn't alone: Big Tech had rewritten childhood and adolescence for her entire generation. Armed with questions and a year to find answers, Ava embarked on a cross-continent investigation into a hidden digital world. She met teens in 12-step programs for social media addiction, young girls wrestling with compulsive porn use, and boys who had been blackmailed by international cybercriminals.

This isn't a self-help guide to digital wellness. It's a survival story from the front lines of 21st century childhood: where young people are re-writing the playbook for what it means to be human in a hyperconnected world.

When she was 12 years old, Ava Smithing spiralled down a social media rabbit hole that nearly cost her life. A decade later, she discovered she wasn't alone: Big Tech had hijacked childhood and adolescence for an entire generation.

In this ten-part investigative podcast, Ava crosses the continent to uncover a hidden digital world. She'll meet teens with millions of followers, young girls wrestling with compulsive porn use, and boys blackmailed by international cybercriminals lurking in their DMs.

In the first episode of Left to Their Own Devices, Ava dives into the debate over technology addiction. The condition is absent from the official list of mental health disorders used by psychiatrists, but undeniable to those who live it. Inside an Internet and Technology Addicts Anonymous meeting, she hears firsthand from people who say their lives have been consumed by screens. And, she sits down with psychiatrist Dr. Anna Lembke – author of Dopamine Nation – who's watched her patient' struggles shift from substance abuse to compulsive relationships with social media, gaming, and online content.

Algorithms are the invisible engines that drive every scroll, swipe or click. And, in the last few years, it's become clear that they can devastate young lives. But Ava discovers they might also be capable of saving them.

She speaks with two teens with radically different stories. When 12-year-old CeCe Neltner went online to find workout tips, her social media feeds devolved into a torrent of eating disorder content. Today, she says she's lucky to be alive. Meanwhile, thousands of miles away, Keira MacDuff was battling a mysterious chronic illness that doctors dismissed as teenage drama – until TikTok's algorithm led her to a life-changing diagnosis.

Did TikTok save Keira's life?

You'd be hard-pressed to find a young person who uses Facebook regularly. But to understand why social media has had such a profound, and sometimes devastating, effect on kids, you need to understand Facebook's origin story first.

Ava tracks down two of Silicon Valley's most prominent insiders: Roger McNamee and Frances Haugen. Together, they trace Facebook's rise into a global behemoth and reveal how decisions made in boardrooms left millions of children vulnerable to social media's most damaging effects.

Ava also speaks with Nir Eyal, author of Hooked: How to Build Habit-Forming Products, who explains how digital platforms are engineered to keep us coming back for more. In Eyal's world, the stickier the technology, the better.

But at what cost to the next generation?

Are screens rewiring kids' brains and creating a generation of depressed teens? After Jonathan Haidt published his mega-bestseller The Anxious Generation, a lot of parents became convinced that they were. But the science tells a more complicated story.

Ava interviews several scientists studying technology's impact on our brains, then takes matters into her own hands. She meets up with Dr. Emma Duerden, Canada Research Chair in Neuroscience and Learning Disorders, to conduct her own experiment: monitoring a teenager's brain activity in real-time while she scrolls through her phone.

What they discover might surprise you.

Like a lot of lonely teenagers, Sarah found refuge on social media. In her lowest moments, she'd reach for her phone, connecting with strangers on Snapchat and Wizz – an app that's been called "Tinder for kids." But those digital friendships quickly became something more sinister. A torrent of older male users solicited her, and then, when she spurned their advances, blackmailed her.

For years, Sarah's life was in turmoil. And then she met a woman named Carol Todd, who took her under her wing. Carol understood what Sarah was going through, because the same thing had happened to her daughter, Amanda Todd, more than a decade earlier.

Now, Carol and Sarah are demanding change. What will it take to keep young women safe on the internet?

The West African cybercriminals who call themselves the Yahoo Boys have perfected dozens of cons – including the infamous Nigerian Prince email scam. But recently, they've discovered something far more lucrative: the extortion of teenage boys.

In just two years, sextortion cases targeting teens have exploded by 18,000 percent. The Yahoo Boys have made millions. And they've left a trail of devastation in their wake that has reached even the most remote communities.

In a tiny Manitoba town, one family is still piecing their lives back together after their son became a victim of a deadly sextortion scam. Their story reveals how quickly a predator can weaponize shame – and how little stands between our kids and catastrophe.

The platforms know about this crisis. Snapchat alone receives 10,000 reports of sextortion every month. Yet the scams continue, largely unchecked.

So one man has decided to do something about it. Cyber analyst Paul Raffile has made it his mission to infiltrate the Yahoo Boys' networks, expose their methods, and bring them to justice – even when no one else will.

In the absence of meaningful regulation, thousands of young people are now looking to the justice system to hold Big Tech accountable. In this episode, we go inside three landmark lawsuits that could finally force social media companies to answer for the damage they've done.

New Mexico's Attorney General, Raul Torrez, has seen the darkest corners of the internet. After twenty years prosecuting child sex crimes, he knows exactly where predators hunt today: social media. In a groundbreaking lawsuit against Meta, Torrez is alleging that Facebook and Instagram have become a "breeding ground for predators". And he's determined to change that.

Meanwhile, in Toronto, Duncan Embury is spearheading a lawsuit on behalf of twenty three different school boards in Ontario. School boards who say that Snapchat, TikTok and Instagram have made teaching next to impossible. Duncan and his team believe that these platforms are knowingly targeting kids while they're at school. And he says that if that doesn't stop, these platforms won't just disrupt education. They'll destroy it.

On the other side of the continent, Laura Marquez Garrett is representing more than 4,000 kids who allege they've been broken by social media. And Laura is seeing some disturbing patterns in their stories. Patterns that suggest – not just that social media companies are harming kids – but that they know it.
