It must be frustrating for an author to write an article but then to have the editor apply a click-baity title that makes no sense.<p>Of course Mapcodes can&#x27;t replace GPS, they tell you where a thing is in relation to other things but not where you are.  I know that the yoghurt is near the milk but that doesn&#x27;t help if I don&#x27;t know where I am in the shop.  I have to ask someone to translate my current position into the same locational namespace and then start to plan a route.<p>Perhaps they will become useful for stating the location of a destination bit under the covers they will always be translated to a linear coordinate system for navigation.
