The COVID-19 pandemic marked a step change in society's reliance on digital infrastructure for information, education, work, commerce, entertainment, and communication. More than ever before, and especially but not only in wealthy countries, adolescents are exploring and expressing their identity and autonomy, including risky as well as creative and constructive opportunities. Born into an already-digital world, their present and future imaginaries presume a thoroughgoing engagement with technology that transcends real/virtual and online/offline binaries. By contrast with older generations (including their parents, teachers, and even researchers), adolescents cannot envisage a return to pre-digital times through any serious limitation of their digital engagement. But, also by contrast with many adults, they can imagine alternative digital futures, and are often keen to discuss how technologies could be redesigned or newly regulated in ways that would better support their well-being and rights in a digital age. As society increasingly pivots towards all things digital and recognizing that the global companies providing digital products and services are becoming hugely powerful in both public and private sectors, governments are making greater efforts to regulate their activities and harness their impacts for the betterment of society. These efforts include turning to psychological and social science evidence for guidance, and listening to the voices of adolescents and those who have their needs and rights in mind.In commenting on the 11 articles selected for this special issue of the Journal of Adolescence on adolescents' digital lives, I reflect on how the findings can inform these efforts and, relatedly, on significant research gaps that future research could usefully address. Let us begin by welcoming the ways in which this issue effectively advances beyond the popular treatment of adolescents as a unitary and homogenous category-often implicit in the celebration of "digital natives" or anxieties about "screen time"insofar as it explores differences among adolescents, including differences in vulnerability. The special issue distinguishes, for instance, more or less lonely adolescents to explore whether going online supports their efforts at emotional regulation (Scott et al., 2023), and whether adolescents' sensitivity to behavioral avoidance or inhibition is a risk factor for problematic gaming (Bradt et al., 2023). Contextual factors also differentiate among adolescents, potentially rendering some more vulnerable than others, as shown by Menabò et al. (2023), who reveal the importance of peer network and school connectedness in mediating the effect of cyberbullying on well-being. There is more work to be done regarding vulnerability. For example, my colleagues and I recently conducted a systematic review of evidence relating digital experiences to adolescent mental health, identifying multiple ways of conceptualizing adolescent digital experiences; yet, even in a literature concerned with clinical population...
