A GPS can guide you to a pinpoint in a featureless landscape where there is nothing to follow on a map.

So too can the stars, or proper time/speed/direction navigation.

I'm not saying GPS isn't useful. I'm saying it hasn't had a life changing impact for the masses that allows for a larger population (eg it's not providing more food, shelter, etc).

You need to medevac a hiker in a remote valley now and your plan is to wait until nightfall and have someone try to navigate by sextant?
