Everyone serious about the outdoors probably does, but lots of more casual people don't. I'm assuming that's how a lot people get lost, because the casual people suddenly decide to try something out of their skill level without knowing it's out of their skill level, because GPS has always hidden their lack of skill. I don't think just buying a map and compass is a guarantee, for the casual people who don't know what they're doing, and the military has entire navigation classes, seems like it's a real nontrivial skill that you have to actually learn. Definitely a good idea to learn, but GPS makes it easy to not know how much you don't know.
