9.5 Human enhancement technologies

Human enhancement technologies are rapidly evolving, blurring the line between therapy and augmentation. These advancements, from cognitive boosters to genetic modifications, promise to expand human capabilities but raise complex ethical and social questions.

As we explore the potential of human enhancement, we must grapple with issues of fairness, autonomy, and human dignity. Policymakers face challenges in regulating these technologies, ensuring equitable access, and assessing long-term risks and societal impacts.

Definition of human enhancement

• Human enhancement encompasses technologies and interventions designed to improve human cognitive, physical, or psychological capabilities beyond typical functioning
• Raises complex ethical, social, and policy questions about the nature of human identity and the boundaries of medical intervention
