I think external investigation will have the edge on self reporting sensor for quite a while, because bringing a xray/ultrasound machine place to place for a yearly inspection allow to split the machinery investment over a lot of structures. > to avoid finding faults too late even before fault discovery there's a lot of value in embedding sensors to tune simulators, so that the next generation product can improve in reliability, material costs or both while being cheaper to design.
