As someone with a degree in geography, this is a bit hyperbolic, and a bit of a one-sided, urban, first world, view of cartography that might be nice for advertisers in big cities with pervasive 4G or wifi, but will also be ignored everywhere else. Mapping is traditionally about sensemaking and placemaking. Precision and accuracy are two different things, and both are entirely context dependent. There's a famous book, How to Lie with Maps, all about it. Maps are how we take things from others by drawing a line in a different place, or how we explore boundaries by drawing what we know and wondering what's everywhere else. They are stories on paper that sometimes have legal or royal or personal meaning, but they are always still stories. Geography is a social science, and cartography is as much art as it is evidence. In Sketching User Experiences, Bill Buxton tells a story about maps, where your Google Glass example breaks down: Imagine that you were kayaking off the coast of Greenland, and needed a chart to find your way. You might have a paper chart, but you will probably have trouble unfolding it with your mittens on, and in any case, it will probably get soaked in the process and become unreadable. From the urban perspective, an alternative solution might be to go to your PC and use a mapping program on the internet... However, there is a minor problem here, too. You don't have your PC with you in the arctic, much less in your kayak. We all know about internet-enabled cell phones and PDAs--they might provide another alternative. Why not jump on the internet using your cell phone, and get the map that way? But here is the problem. You probably can't get cellular service where you are in your kayak. And even if you can, your battery is probably dead because it is so cold. Or, your phone won't work because it is wet. Even if your mobile phone does work, and you have service, you probably can't operate it because you can't do so without taking your mittens off, and it is too cold to do so. Now let's look at a third approach, one that the Inuit have used... This shows two tactile maps of the coastline, carved out of wood. They can be carried inside your mittens, so your hands stay warm. They have infinite battery life, and can be read, even in the six months of the year that it is dark. And, if they are accidentally dropped in the water, they float. What you and I might see as a stick, for the Inuit can be an elegant design solution that is appropriate for their particular environment. There are entire cultures where your Euro-centric view of mapping does not compute, so much so that researchers at my alma mater would go into jungles and teach third world tribes how the usurping white man views their world so they can make maps that you, the outsider, can understand what they had previously only expressed emotionally. There are entire continents where your "Mirror World" cannot accurately represent anything, and I feel that puts your seminal moment much further away than you imagine.
