In this interview, Lenny Rachitsky talks with Adam Mosseri, head of Instagram, about how AI is reshaping product development, the enduring importance of human taste, and the practical challenges of scaling AI‑driven features. Mosseri explains Instagram’s shift to AI‑powered product pods and staff roles, the need to budget token and compute usage, and the creation of the embedding‑based recommendation system known as “Your Algorithm.” He discusses how AI informs strategy, execution, and road‑mapping, and how hiring decisions must balance technical expertise with design judgment. The conversation then moves to the complexities of running large‑scale experiments: a conflated feed redesign test that sparked creator backlash, the necessity of a proactive communication strategy, and cautionary lessons from pricing experiments at Anthropic. Mosseri shares two personal failure stories – the ill‑fated Facebook Home project and the early version of Reels built on top of Stories – highlighting how mis‑aligned foundations and timing can derail products. The interview also covers Mosseri’s personal approach to screen‑time and digital boundaries for his three children, emphasizing education, approved apps, and the importance of AI literacy. He describes coding with his 10‑year‑old using Cloud Code and “vibe coding,” advocating for balanced exposure to technology. Finally, Mosseri urges listeners to remember the trade‑offs inherent in tech decisions, to engage critically, and to recognize that behind every product are people navigating complex choices.
