Dr. Killeen builds on the idea of deep versus surface knowledge by exploring an important question: what happens when we begin outsourcing not just our tasks, but our thinking? As AI becomes a bigger part of everyday life, it's worth asking which skills we should delegate and which ones we need to keep strengthening ourselves. Using examples from dentistry, leadership, and technology, he explains why tools like AI should amplify good judgment, not replace it. Just as a bicycle or motorcycle makes a rider more capable, the value of AI depends on the person using it. In this episode, Dr. Killeen shares why protecting your ability to think critically may be one of the most important habits you build. The best tools can make you faster, but only if you're the one steering.
