"AI-first" has become a badge of honor. It should be a warning label. A company that puts the model before the human building trains itself to solve problems no one has; shipping impressive technology that misses the person it was meant to serve. This session argues that the AI only works because of people, and that human-centered product thinking isn't a nicety, it's how you avoid confidently building the wrong thing. We'll cover how to keep customer reality upstream of technical possibility, and how to know your product actually fits. You'll leave with a mental model that turns "people first" from a slogan into a design discipline.
