Gemini 4 Carbon is currently the top-ranked model on public benchmarks, and Google's own product directors are restructuring how they work around it. Jaclyn Konzelmann, a product director at Google Labs, tells Peter Yang exactly how her PM job changed after Gemini 4 shipped, starting from the first minute of the conversation.
The interview covers three concrete areas: internal product development workflows, documentation quality control (specifically how Konzelmann's team filters AI-generated slop from specs and docs), and personal use cases across raising three kids. The slop-prevention angle alone is worth the full watch. Most teams using AI for docs have no guardrails. She does.
What makes this worth reading in full is the inside view of how a Google Labs PM answers the question 'should this product even exist?' with AI in the loop. That segment starts at 2:11. The gap between how AI is marketed and how it is actually used internally at the companies building it is the real story here.
