Men take their misfortunes to heart, and keep them there. A gambler does not talk about his losses; the frequenter of brothels, who finds his favorite engaged by another, pretends to be just as well off without her; the professional street-brawler is quiet about the fights he has lost; and a merchant who speculates on goods will conceal the losses he may suffer. All act as one who steps on dog dung in the dark.
SF has never really aimed to tell us when we might reach other planets, or develop new technologies, or meet aliens. SF speculates about why we might want to do these things, and how their consequences might affect our lives and our planet.
