Complexity is a mismatch between the information that an observer can possibly gain from (or inject into) a system, and the "size", autonomy, and generativity of the system itself. Sometimes this mismatch is intractable or irresolute. Rather than looking for specific examples of complexity, if people are being glib about how "easy" complex systems are to "solve", you can bring up Wicked Problems, which tend to be about the state of complex systems. https://en.wikipedia.org/wiki/Wicked_problem https://en.wikipedia.org/wiki/Wicked_problem The field of Failure Studies tends to be about complex systems. The book "Drift Into Failure" specifically talks about how our default mechanistic interpretations of systems tends to mislead us into believing things fail for singular, spectacular, and simple reasons, when in many large-scale systems they fail through a compounding of innocuous events.
