This has led to a small but growing movement to make the workplace take on this issue, with the premise that traditional, pre-digital work processes tended to have more people directly in the loop, reviewing, editing, overseeing, and so on. Now too often, work takes place in digital silos that greatly reduce the human involvement, fails to capture much of the knowledge at all (something I call knowledge evaporation), and leaves little behind to learn from, build upon, or otherwise reuse. This is because older digital tools aren't nearly as focused on discovery, collaboration, or network effects.
