The boulder is going to fall off the cliff.  The question is when?  It is easy to think of the boulder as the greatest threat to our future.  Perhaps we can design an app with 24-hour monitoring to alert us of any movement, build bracing and a cable retention system, or move our operations.  Or, we can assess the probability of failure and then move forward with the work that matters.  Too often the boulder consumes our attention, when in all reality it may stay perched for another decade.  What would a decade’s worth of distraction cost us?
