Have you ever wondered what happens when a child starts talking to an AI like it's a friend? In this episode I sit down with Dr. Mathilde Cerioli, a cognitive neuroscientist and Chief Scientific Officer at the nonprofit everyone.ai, to unpack what AI companions actually are, what they do to a child's developing brain, and why preteens and teens are especially drawn to them.

Mathilde explains why an AI can feel so social and so sticky, why the friction of real friendship is a feature of development rather than a flaw, and how the way an AI talks can quietly reshape the relationship a child thinks they can have with it. We get practical too: the red flags and green flags to watch for, why kids often turn to an AI instead of us, and what to actually say if you discover your child has been chatting with an AI companion for months. The throughline is simple: lead with curiosity, not panic.

What you'll learn

What an "AI companion" really means, and how it differs from ChatGPT or Gemini
Why the preteen and teen brain is primed to treat anything social as rewarding
Why friction and "productive struggle" in real friendships build social skills an AI skips
The difference between an AI that supports a child and one that "sucks them in"
Red flags and green flags for AI use at home

A simple gut-check to teach your kid: "Am I running with AI, or is AI running for me?"
What to do in the first 24 hours if you find out your child has been using an AI companion

About the guest

Dr. Mathilde Cerioli is a cognitive neuroscientist (PhD, Université de Montréal) and Chief Scientific Officer at everyone.ai, a nonprofit focused on the opportunities and risks of AI for children. She began her career as a child neuropsychologist studying how environments, especially digital ones, shape who children become. At everyone.ai, and in partnership with the Paris Peace Forum, she helped launch the Beneficial AI for Children Coalition, a multistakeholder initiative working with governments, tech companies, and organizations including UNICEF, UNESCO, and Common Sense Media.

Moments worth remembering

"That friction is not a bug. It's really a feature of development. That's how they learn to adjust."
"Am I running with AI, or is AI running for me?"
"You could have good advice, but depending on how it's said, it really matters in how it frames the relationship."
On a teen who pulled back from an AI companion: "I was grieving that relationship, even though it was an AI, even though I knew it was not human. That system was the only one to know about me."
"If your first reaction is panic, have the conversation the next day. But do have that conversation."
"We've run an entire social experiment on a full generation. With generative AI, we got a chance to learn from that."

A quick ask

We're running a short survey on how parents are using AI with their children. It takes a few minutes and your answers genuinely shape this work: parent research survey
