Due to the rapid advancements in science and technology, commonly referred to as the Fourth Industrial Revolution, it is plausible that humans and intelligent robots will coexist in the near future, resulting in new social changes and problems that call for continuous exploration and analysis. As a result, in the Fourth Industrial Revolution and the post-human era, it is inevitable that the underlying inquiries of what is a human being and further who is a human being will re-emerge. This paper explores the coexistence of technological creatures such as androids and clones in the science fiction short story “After Yang” by Alexander Weinstein. It also examines the otherness of androids and clones as they enter the realm of human physical, mental, and emotional labor, and analyzes how ongoing racism is portrayed in the story. By discussing the concepts of post-human and post-race, the paper analyzes communities of emotion and memory, the evolution of race perceptions, and the imperative for coexistence. Ultimately, it concludes that “After Yang” prompts readers to consider whether a future of post-human coexistence and post-racial mutual acceptance is possible in a constantly evolving world.
