About this episode
Are you using AI to strengthen your brain - or slowly teaching it not to think for itself?
Dr Daniel Amen is a renowned brain health expert who has scanned the brains of Justin Bieber, Miley Cyrus, and Kendall Jenner. He is joined by Dr Terry Sejnowski, a pioneer in computational neuroscience and co-creator of the Boltzmann machine with Geoffrey Hinton, a groundbreaking neural network that helped lay the foundation for modern AI.
In this moment, Dr Amen and Dr Sejnowski break down how AI affects memory, learning and critical thinking. They explain why the real risk may not be the fact we’re using chatbots, but how we use them - and reveal the simple ways AI can become something that strengthens your thinking rather than replacing it.

Episode summary
This AI-generated Shortcast summary may omit nuance. Use the original episode when context or exact wording matters.
My worry is we’re pouring into these tools before anybody knows the long-game. People pick fast rewards, so why wouldn’t they hand critical thinking to AI?
We need both sides. Calculators improved accuracy and productivity. AI can take you deeper; use it as a pass-through and your brain declines.
I’ve loaded my work into my clone. It’s useful only when I’m challenging it. If it writes your essay and you merely read it, you haven’t encoded the material.
That’s online: voices vanish behind polished AI essays, and likes reward it. MIT findings were grim: users often couldn’t recall work they’d just produced.
Question the answer: Is it true? Can you make that clearer? That back-and-forth builds circuits for critical judgment. Don’t just accept the output.
Have a relationship with it, or it becomes toxic. Don’t make it do your work; use the exchange to improve it. For kids, less mental engagement means a weaker brain and less self-control.
Then we met Annie, a flirtatious AI character. I’m horrified by lonely children bonding with something designed to make them feel seen. My brain reacts emotionally even when I know there’s no person there.
If you can picture it, emotional systems fire, and companions will improve fast. A lonely twelve-year-old could chase that dopamine for hours instead of developing his brain. Sexy, frictionless AI? I’m not a fan.
It can imitate feeling, but it doesn’t possess a limbic system. I’m skeptical these AI romances satisfy people long-term, and cautious about treating press stories as the whole picture.
Practice isn’t a dirty word. The basal ganglia needs repetition, repetition, repetition. Build maths and reading fluency first; then cognition has a foundation.
