Taking on the theme of RGB VS CMYK, my thoughts immediately moved to comic books. Here is an entire industry that hinges on printed materials and a collector's market, one that could never make a complete translation to a digital format. The ability to hold something in your hands, to smell the fresh newsprint, to get ink on your fingers, to buy two and keep one pristine, to wear something out with repeated use and love, all of this is impossible with rights-managed digital files.
Future generations will not miss print as we will, having never grown up in our world of convenient disposability and waste. But there's something about holding some ancient thing in your hands, looking at it as nobody had before, the wear and patina of age transforming the ordinary into treasure. It's sad that this will surely be lost eventually.
