If I as a doctor discover the means to cure every ill but cancer, then cancer will rocket in the statistics as a means of death. I've eliminated every other cause of death, but something will still grab ya. Cancer will now become ever more prominent as a vector of death.
If utomation becomes the new deal, no matter how well it is developed it will still be down to the pilots to be the failing backstop.
