Imagine being proud of skills which have become obsolete in the last century for the vast majority of uses. Reminds me of the people whining about the loss of cursive writing skills, and cursive at least makes writing long texts more hand-friendly. I can read and use maps (if i ever again wanted to) but they neither update, don't fit neatly in my pocket, suffer from wear and tear (funnily enough they suffer from water damage a lot more than my smart phone, which i forgot i had in my swimwear - i was around 1 1/2 hours in the water, and after blowing some air in the USB-C port, everything was still working. Try that with a paper map, i dare you), don't deliver context or images of the surroundings, do not have turn or lane info, completely miss important data like construction work or road blockages and are unable to provide you with traffic data.

Even for non-navigation stuff paper maps are wildly unpractical compared to the digital alternative. City planning, construction work and the likes all need easily updateable, versionable maps that do not distort the size of things like mercator.
