Pilots have always grown more dependent on new technology as it proves its reliability over time. In the 1950s and 1960s, VORs replaced NDB technology, which had, itself, replaced the four-course range of the 1930s. As to the argument that today's avionics are no safer than older tech, I submit we've increased utility, not safety per se. It's now fully prudent to launch innumerable flights that would have been downright foolhardy without the autopilots, terrain alerts, synthetic vision, on board weather (etc., etc.) that we have today. As for the screens going blank — yes, always assume it could happen and know what you need to do and where you need to go to find a safer haven in the storm. There will always be a baseline of accidents caused by judgment errors — pilots simply getting in over their heads. With new avionics, we've changed exactly how it is they do this, but that's all it is. Being human, pilots will always make mistakes in some form, and unfortunately, some of those mistakes will be deadly.
