Because happily it’s not all about something’s utility. From another perspective, the fact that human beings can’t hear something is inconsequential. It’s also about technological innovation, about being able to reproduce reality as faithfully as possible, about the state of the art, about leaving behind human artifacts that are as perfect as possible. Amir played a high-res file that looked absolutely gorgeous up past the threshold of human hearing (until the vocal track kicked in, which was not as pristine as the instrumental one), and I just think it’s great that something like that exists. Maybe one day human hearing will be able to make full use of it.How about a properly implemented 44.1/16 A/D - D/A chain and everyone goes home happy, like it was meant to be all along?
