Technological advancement has made the world a complex arena of day to day transforming phenomenon. In such a complex and technologically progressive world nothing is static instead things have become technology oriented. The socio-historical phenomena like orientalism and imperialism are also not free from technological progress. Similarly, literature of the contemporary times has become Postmodernist for it now aims to represent the current human experiences. The quality of the Postmodernist literature is to represent and dismantle the socio-cultural constructions that use to perpetuate control and power. The objective of this research is twofold; it has projected the world of technological progress and innovation through the analysis of the selected Post-cyberpunk novel Accelerando (2005) by Charles Stross, The Windup Girl (2009) by Paolo Bacigalupi and The Rapture of the Nerds (2012) by Cory Doctorow and Charles Stross. Socio-Cognitive analysis (van Dijk, 2008) has projected the linguistic discursive analysis of techno-colonialism in order to answer the research questions. The study has also introduced Post-cyberpunk as the genre of Postmodernist twenty-first century literature. The findings of the research have suggested that the selected Post-cyberpunk novels have not only represented techno-colonialism but they have also characterized the impact and influence of the techno-colonizers throughout the world.
