Waymo's Dmitri Dolgov: The Demo Is Only 1% Of The Work

WOW Mentor breaks down the discipline of execution that sits between the magic of a demo and the brutal reality of a product. Across seven lessons drawn from nearly two decades of putting physical AI on real roads, Dolgov explains why a working demo is only 1% of the work, why reliability grows 10x more expensive with every nine on the ladder, and why the long tail becomes the whole problem at scale. He shows how the required nines dictate the architecture of sensors and the Waymo foundation model, how the bitter lesson governs the use of structure, and how a closed-loop simulator plus an agent-simulator-critic flywheel accelerates progress. His final claim is the sharpest: eval, metrics, and the trust earned by proving safety in the field every single day are the one advantage rivals cannot copy.
