Excellent point. For many years I made a living automating very complex
workflows and the clients would always ask why I would come up to 90-95%
automation and stop there. Thoroughly automated systems are brittle and when
something does go wrong the failure is usually much more severe than lightly
automated systems. So I always left something intentionally un-automated at
critical points to engage humans and bring in human judgment and
observation. This made the system harder to design/develop but paradoxically
easier to operate and maintain.

Design is how it works.
