Adam Mosseri, who has run Instagram since 2018 and overseen its growth past 3 billion users, tells Lenny's Podcast that Meta is actively dismantling the classic product team structure. Baker's-dozen specialist teams are being replaced by pods of four to six generalists. The emerging role is 'product staff': one person blending PM, design, data science, and research. Mosseri is explicit that functional boundaries are dissolving, and that some specialist roles face real career risk.
Two other claims demand attention. First, Instagram's recommendation algorithm is only now reaching the sophistication users assumed it had years ago, meaning the paranoia about what the app knew was premature but is becoming accurate. Second, Mosseri argues AI-generated content is a tailwind for Instagram, not a threat, because it increases the volume and variety of content in the feed while simultaneously raising the value of verified human creators. That tension between synthetic volume and authentic identity is the core strategic bet he is making.
The conversation earns a full read for its specifics on how Meta actually accounts for AI token costs internally, where Mosseri draws the line on human judgment versus model output in strategy work, and his post-mortem on two named failures: Facebook Home and the first version of Reels. His framing of great product leaders as curators rather than generators is a concrete argument, not a platitude, and the reasoning behind it is in the transcript.
