I always think of comparisons to aviation. There are a million and one things that can go wrong when flying a plane, but it's still one of the safest ways to travel. That's because regulations and safety standards are to such a high degree that we simply don't consider injury or death an acceptable outcome.
Whenever someone says "as long as it's better than a human", that's where my mind goes. We shouldn't be satisfied with just being better than a human. We shouldn't be satisfied with five nines! I don't really care about what courts have a problem with — my point is just that our goal should be zero preventable deaths, not just moving from humans to AI once the latter can be better on average than the former.
