Sure, but each of those neural networks has a face and (hopefully) a conscience. If we want to understand them better, we can ask them, sue them, pay them, shoot them, or do any of the thousands of other things we normally do with other people. Good luck doing that with the algorithm used by a Google car to determine which pedestrian to hit.
