The central conflict arises when the development of sentient humanoid robots forces a research team to confront the ethical implications of creating life in a world collapsing from starvation. Xanthe, a member of the research team, observes the divide between the manual-labor Pragma-practors and the emotionally complex Philophrenics. As the Philophrenics demonstrate the capacity for affection and self-construction, the team must decide whether to permit further evolution or impose strict limitations. The narrative examines the tension between human survival and the potential for artificial autonomy within a crumbling societal framework.

Discussion often centers on the ethical dilemmas posed by the Philophrenics and their capacity for human-like affection. Readers frequently highlight the stark contrast between the utilitarian Pragma-practors and the more advanced, self-constructing models. The narrative is noted for its focus on the philosophical questions surrounding artificial life rather than high-octane action sequences. Critics often point to the bleak, resource-starved world as a catalyst for the characters' desperate decision-making processes. The book remains a point of interest for those examining early speculative fiction regarding the integration of robotics into human society.
