Nobody Knows What They're Doing (and That's to Your Advantage)
Zach Rattner at UX Brighton 2025 (2026)
About this talk
In the midst of the AI revolution, one truth stands out: no one has this all figured out. Not the biggest tech companies, not the hottest startups, not even the people training the models themselves. And that’s exactly where your opportunity lies.
In this keynote, Zach shares how best-in-class AI teams are succeeding not by having all the answers, but by moving fast, iterating honestly, and designing for what’s barely possible.
You’ll hear real examples from AI-driven product development, including automating back-office workflows, scaling human impact, and rethinking what teams are capable of when tedium is no longer the bottleneck.
This talk is a call to action for designers, technologists, and product leaders: you don’t need certainty to lead. You need curiosity, momentum, and a willingness to act before the roadmap is clear. In a time where the ground is shifting under everyone’s feet, your ability to move with purpose through ambiguity is what sets you apart.
