Consider the transformation of ditch-digging from a relatively slow and somewhat imprecise process involving several ordinary shovels, much labor effort, and low skill levels to a faster and more precise process often involving a single power digger controlled by a skilled operator.
Power diggers are very slow and require low skill levels.
