The problem with trees Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as: HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS only to find a reference to another leaf: Please see HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.

Hints towards a non-extractive economy An Article by Matt Webb interconnected.org There’s a movement called the circular economy which is about designing services that don’t include throwing things away. There is no “away.” A non-extractive economy is going to look very different to today’s economy. These points feel opposed somehow but they are part of the same movement: With CupClub, it’s all about infrastructure. With the battery-free Game Boy, it’s untethered from infrastructure: once manufactured, no nationwide electricity grid is required to play. We’ll need better tools to track and measure. There will be new patterns for new types of services. New technologies to build new products. New language. So it’s fascinating seeing the pieces gradually come together.
