Stanislav Lem began as a writer of realistic prose about the war - but eventually preferred fiction. Behind this choice was different: hopes for the possibility of the genre, and certain censorship restrictions. Then Lem was terribly annoyed that he was perceived as a science fiction writer and did not read what he had laid down.
Has the situation changed much now - especially in Ukraine? It's no secret that science fiction is sometimes perceived as entertaining or teenage reading. And sometimes they have reasons for this - but not always!
