Better humans?: The politics of human enhancement and life extension

Abstract

Human enhancement technologies, including pharmacological cognitive boosters, genetic interventions, and methods for radical life extension, represent a shift in human biological development that blurs the distinction between therapy and improvement. Proponents suggest these advancements are a logical extension of human ingenuity and may lead to a posthuman state characterized by superintelligence and the mitigation of senescence. However, the transition toward biological modification introduces significant sociopolitical risks, notably the potential for a marginalized “unenhanced” underclass and the exacerbation of global inequalities. Ethical challenges involve the medicalization of social behavior, the potential for coercive enhancement in competitive environments such as education or the workforce, and the potential devaluation of human life within a disability-rights framework. Governance of these emerging fields requires proactive, “upstream” public engagement to ensure that technological trajectories are shaped by democratic deliberation rather than market or technological determinism. Furthermore, an overemphasis on cognitive maximization may come at the expense of emotional intelligence and social cohesion. The successful societal integration of such technologies depends on balancing individual autonomy with the preservation of human dignity and ensuring that the pursuit of biological optimization does not undermine the normative foundations of inclusive communities. – AI-generated abstract.
