Bruce Sterling did an interview with Chuck Olsen of Rocketboom for today's episode and he focused on the value of metadata regarding shoes. Well not just shoes but mainly consumable products who, in fact, spend the overwhelming majority of their life in a trash heap after they are rendered useless (or out of style). The value of products is not lost - simply diminished and we are throwing out much value when we discard raw materials such as leather, rubber soles, and cotton laces. In a sense we are taking recycling to the next level by making us completely aware of the contents of our objects. The idea of Spimes is tracking object through space and time.
He continues on to make commentary on the goods and evils of a tagged / metaverse world. His points are interesting and very valuable to those interested in the field. Go watch the video!
