Using GPS instead of maps is the most consequential exchange of technologies in history

I learned map reading in the Boy Scouts. Many years later I learned to trust natural navigation while doing solo night dives in both Monterey Bay and the Channel Islands. I would check my compass upon descent and then not look at it again during the course of hour-long scuba dives ---- never got lost.
