One of the important things I've learned from working in technology, is that technology sometimes doesn't work. I've seen people unable to charge their cars on ChargePlace Scotland because they didn't have phone signal and hadn't thought to get the NFC card, for example. When it comes to something as important as protecting your life, you really should have a low tech backup. The top of Ben Nevis is in cloud most of the year, and sometimes visibility can get very poor very quickly, but if you walk the wrong direction from the summit you could easily fall off a cliff, so you really do need a map and compass to increase your chance of getting down safely. It's just common sense. I don't think it is necessarily a generational thing though - there have always been people from all generations who lack common sense.
