For over 30 years, @JimKwik has coached Hollywood, professional athletes, political leaders, and Harvard University on how to learn faster and think sharper — and in this episode, he tackles the question sitting underneath so much of modern life: what happens to your mind muscle when every cognitive task gets handed off to ChatGPT or Claude?
The good news: your brain, like your muscles, adapts to the demands placed upon it at any age or stage. Jim explains why frustration and failure aren’t obstacles to brain training, shares his personal top ten list of brain-building habits, ranging from racket sports to language learning and volunteering. He also delves into an MIT study examining the impact of ChatGPT and introduces his own framework for using AI as a genuine cognitive partner, rather than a replacement for human brain power.
