{{a|systems|{{image|dancing landscape|jpg|A dancing landscape, yesterday.}}{{subtable|{{complex capsule}}}}}}[[All other things being equal]], a bummer — if you have in mind ''[[risk]]'' — and a boon — if you have in mind ''reward''. A violation of [[Occam’s razor]]; a source of confusion, a time-sink, a material contributor to catastrophic [[normal accident]]s; a ''[[waste]]'' — yet in a [[distributed network]] of autonomous bodies, an ''inevitability''. The more sophisticated the group of individuals, the greater the rate of complexification.
 
There are those [[Deterministic|determinists]] who see complexity as just a sort of presently-uncalculatable state of a simple algortithm, like [[Conway’s Game of Life]]. We do not agree.
 
====Complexity as a bummer====
*Chernobyl
*Space Shuttle Challenger
*Any financial calamity you care to mention
 
====Complexity as a boon====
*T’Internet
*The gradual disintermediation of [[information]] from its [[substrate]]
*[[Jacquard loom]]
 
===[[Complicated]] versus [[complex]]===

Things can be merely [[complicated]] without being [[complex]]. ''Complicated'' problems are naturally difficult, but you can solve them with rules and [[algorithm]]s. The systems and processes, by which The Man commands and controls employees can manage this kind of ''complicatedness''.

*{{simple capsule}}
 
*{{complicated capsule}}'''[[Complicated]]''': complicated systems need skilled management, but the right hands can usually manage them successfully. You know you have a complicated system when there is a comprehensive and robust set of axioms and rules, and thus it is a matter of making sure that the proper models are being used for the situation at hand. [[Chess]] and [[Alpha Go]] are complicated, but not complex, [[systems]]. They’re ''not'' [[wicked environment]]s. Do you hear that, {{author|Daniel Susskind}}?
{{simple capsule}}
*{{complex capsule}}'''[[Complex]]''': Complex systems are dynamic, constantly changing, and interact with themselves and the environment in unexpected ways. They may comprise multiple other simple, complicated and indeed complex systems interacting with each other. So step one is to manage the simple and complicated sub-systems as effectively as possible — deploy checklists, simplify, homogenise — but even after that you are ''still'' left with a system which is innately unpredictable. It will do unexpected things. Like blowing up. So have your plans for dealing with those [[normal accident]]s.
