The following is the conclusion from the chapter Simulacra and Science Fiction. I did not understand it, and such a specific categorization seemed unusual to me. I was hoping someone might be able to elaborate upon on it or explain it in a different way.
"Between the operatic (the theatrical status of theatrical and fantastical machinery, the "grand opera" of technique) that corresponds to the first order, the operative (the industrial, productive status, productive of power and energy) that corresponds to the second order, and the operational (the cybernetic, aleatory, uncertain status of "metatechnique") that corresponds to the third order, all interference can still be produced today at the level of science fiction. But only the last order can still truly interest us."
