Extropy is the opposing concept of entropy. It denotes the idea that culture and technology will aid the universe in developing in an orderly progressive manner. So in turn extropy is the tendency of systems to grow more organized. The idea was first introduced by philosopher and futurist Max More in the late 1980s.
The term was first coined to serve as an antonym of entropy, replacing its prefix (representing the prepositional prefix ἐν en, “in” in its Ancient Greek etymon ἐντροπία entropía “a turning towards”) with ex- (representing the Ancient Greek ἐξ ex “out of”, “from”); although, because ἐξ eks takes the form ἐκ ek when prefixed to an element beginning with τ (t), the analogical spelling is ectropy (or ektropy), as if from Ancient Greek *ἐκτροπία (ektropía “a turning out of”).
