This is just as true for Human pilots as well, there are plenty of judgement calls and scenarios average pilots also will fail . Are the autonomous systems better than our best, most experienced pilots? not yet. They are however likely already better than the average pilot. Updating the autonomous software to factor in new scenario is easier than grounding pilots and getting them retrained on the simulator The expense and availability of type certification and simulators is one of the reasons the 737 MAX was designed to handle like the older model, although it was fundamentally different. After the fixes, if the FAA require separate type rating it will be very expensive and slow process for all airlines. The autonomous systems will behave consistently under a given scenario, human responses and errors may vary. Fixing the former is easier than quality checking the later. Planes already fly a lot on their own, they also crash on their own already too, due to software bugs or faulty sensors, 737 MAX is software bug from a faulty sensor reading on the autonomous system after all. It is a blurry line between what we have and a fully autonomous system. The risks are already there, might as well embrace it and test the software lot more rigorously than depend on the human to intervene and override as we do now.
