So does work like this essentially mean there will always be strange edge cases in AI algorithms so that they will never be 100% accurate? Which means the AI driven cars and robots will also never be perfect at navigating the world? What degree of accuracy would we ever be comfortable with? The current metrics for AI seem too simplistic, there needs to be several new and better ways to understand how functional an AI is. 99% accuracy in classification sounds great until you realize that means your car will hit something one out of a hundred times. How can you objectively say an AI is a better driver than most humans? Is the self-driving vehicle industry developing standards or is it all just trial-and-error based on human observers?
