Human is no longer a pure and ultimate entity in the universe. With the rapid advances in science, technology, cybernetics the universal human nature has been placed today before a big threatening question mark which challenges the anthropogenic existence of human subjectivity. The British colonizers once shaped and formed the geopolitical intellectual identity of colonized others through education according to their own, so to make the colonized useful for them. But through this process of learning and shaping the colonized others get able to form a rebel against the colonizer. In the same light, we, the so called human with the help of our developed brain shape a useless material to make a useful tool for our own use. But, consciously or unconsciously we become a victim under the colonial claw of that tool which is more powerful than the human capability. This colonial impression made by the machine, tools, technology upon the human reminds us of the fact that human does not control machine or technology, rather the opposite. This actually results in hybridism with an exotic obsession with technology and machine which makes a ‘man’ ‘posthuman’ (cyborg) and in the study of posthumanism. The discussion in the paper t hrough a postcolonial lens will simplify the fact how digital and technological existence of human overpowers/colonizes the physical entity of human and through this process also will investigate the possible crisis and ‘end’ of a certain conception of human or the humanist notion of ‘human’ including reference to novels by H.G Wells, E.M Forster, Ray Bradbury, Octavia Butler and others.
