Genetic modification in humans raises several ethical and societal concerns. Ethically, it poses questions about the limits of human intervention in natural processes, particularly regarding the potential for "designer babies," where genetic traits are selected for non-medical reasons, such as physical appearance or intelligence. This could lead to a new form of inequality, where only those who can afford genetic enhancements benefit from them, exacerbating social disparities.
Societally, it could challenge concepts of human identity and individuality, as people might no longer be considered "natural" but rather products of genetic engineering. Additionally, there is concern about unintended long-term consequences, as modified genes could be passed down to future generations, potentially affecting the genetic makeup of the entire population. Furthermore, the possibility of gene editing being used for harmful purposes, such as eugenics or discrimination, adds to the complexity and potential risks associated with human genetic modification.
