From a technology perspective this novel holds up remarkably well for something written in 1973 (Most likely due to the relatively minimal descriptions of technology), and the writing is still pretty solid.
The combination of utopia/dystopia and post-apocalyptic elements puts Children of Morrow
solidly within an existing body of literature that's pretty popular and likely to remain so for quite some time. There are aspects of the writing that give a definite timestamp to the novel (for example, everybody
seems to be wearing a jumpsuit in the advanced-tech society), but they aren't so glaring as to throw readers out of the story.
