So many of these genres are applied to works long after they have been completed. For example, The Flintstones are labeled as stonepunk, even though it originally aired in the early 60s.
Jules Verne wrote steampunk a century before the term was even coined. Cervantes wrote a novel before novels were a thing (at least in the West), and thereby defined what a novel should look like.

That's not the only encounter with "advanced" technology; there's also the episode with the water-powered "fulling-hammers" https://www.cliffsnotes.com/literature/d/don-quixote/summary...
Don Quixote also rails against modern military technology like firearms.
Compare this to, say, Dinosaurs, which (while in many ways similar to The Flintstones) had actual references to contemporary events and phenomena.
