In a 45-minute Behind the Craft episode, Brilliant co-founder and CEO Sue Khim (10M+ learners) explains how AI can make kids smarter instead of just making cheating easier. Highlights: grades are up while test scores are down; Brilliant's AI tutor 'Koji' is built on the principle of never giving the answer, with a real tutoring session played back; humans design lesson principles while AI builds lessons, tested on simulated students and measured by learning outcomes rather than completion; plus her rule for competing with big AI labs and raising kids who enjoy hard things.
