The social networks as exponents of the notion of techno-mediated communicative ecosystems have become paradigms where human life moves at the dawn of the 21st century. Their influence in defining what is considered life and how human life is managed is beginning to be glimpsed and discussed. A human group that has been characterized by the use and appropriation of social networks due to its versatility and adaptability are adolescents. However, reflecting on the ways in which social networks and techno-mediated ecosystems influence the construction of personal identity as a contemporary moral problem is essential to deliberate on the impact they have on the conception and conceptualization of current meanings for categories such as identity, individuality and participation. This is how the question arises: are social networks adequate or inappropriate scenarios for the process of construction of personal identity in adolescents? In the case of adolescents, the uses and appropriations of social networks should not be accepted in an aseptic manner nor absolutely rejected when analyzing and weighing the impacts that these digital networks have on the construction of their personal identity. Therefore, spaces must be generated so that, from the recognition of emotions as elements that guide judgments and forge values, associated with the relational capacity of an individuality based on the experiential and interaction with others, adolescents can give the transition from a digital heteronomy to a digital autonomy. It is here that Bioethics is invited to shed light, to be interested as a space for deliberation and convocation to reflect on this phenomenon of anthropic life where new forms and expressions of the human condition are being configured in the 21st century.
