Waymo Co-CEO Dmitri Dolgov: The Demo Is Only 1% Of The Work

The gist

1. Getting from 90% reliability to superhuman performance requires roughly 10x more effort for each additional nine, like 99% then 99.9%.
2. Dongov says every AI hype cycle makes demos 100x easier but leaves the hard reliability tail unchanged, so founders should count required nines before picking an architecture.
3. Waymo uses cameras, lidar, and radar together so each sensor covers the others' weaknesses, such as cameras failing in darkness or radar struggling with fine detail.
4. Dolgov argues that defining what safe enough means in numbers, before building, is more strategically important than which model architecture you choose.
