Speculative
Speculative fiction could be thought of as a pretext for many discoveries today. The best example is science fiction by Jules Verne. When he wrote Twenty Thousand Leagues Under the Sea, the world did not know about submarines and other elements of technology that appeared, for example, a waterproof monitor. Furthermore, the first robots appeared in the narratives of E.T.A Hoffman and in stories for children by Lyman F. Baum in the 19th century. Also, in one bad dystopian novel in the 21st century, for the first time, a character appears that carries headphones in the ears, which are a common occurrence today.
