There'll always be a place for it.
I like new technology that makes life easier, but I don't think I've ever owned or used an electronic device that didn't malfunction in some way at some time.
Knowing you can deal with loss of gear (GPS being the most notable one these days I think) without totally losing the plot is good.
Plus, it's just good airmanship to be able to check if the automation is telling you bull****, be it because of equipment or operator failure, or both.
