Role of Maps

Having a degree in Geography has never been a strong calling card, my minor in Economics has always been better on the resume.  But GPS's and google maps have made cartography almost redundant.

Historical Maps used to convey data in a way words cannot.

The calculator and spreadsheets made everything above checkbook math redundant. GPS and electronic directions (Tom-Tom and others) have made map reading redundant.
.
And so I wonder if map making goes back to the pre-cartography days.  In the example above, the physicality of the map is secondary to the information provided.  This map conveys both the scope of the Holy Roman Empire (outlined) and the fractiousness of it (the different entities contained within the outline).
.

To the left is an even more extreme example.  This is a map of the Mid-East Holy Lands.  It is designed for use by Sailors to identify cities with harbors, and closest anchorage to interior cities.
.
We would label this particular map inaccurate on many levels (interior distances, north / south alignment, political affiliation, etc.).  But it was designed for a specific purpose and interior accuracy wasn't as important as shoreline landmarks.
.
In the olden olden days, maps were commissioned to pay tribute to a country or ruler, so the accuracy of the map was secondary to the prominence of the patron's data.
.
Anyway, I wonder where the future of cartography lies.  Or if there is a future. Do Cartographers go the way of Alchemists?
