Values play a central role in technology design. But beyond acknowledging the politics of technology, questions remain around where those values are coming from, which values we need, and how they play out and shape the socio-technical systems we create. New challenges such as the climate crisis and societal polarization call for technologists to become part of the public and political arena. This results in a new sense of responsibility, but the closing of CPSR, the Computing Professionals for Social Responsibility, has left a gap. Today, across tech workers, academics and computing professionals, there is a renewed sense of urgency for engaging the public and politics to change course in how computing shapes society. What should a CPSR for the 21st century look like? This interactive workshop aims to re-invigorate the debate around values and social responsibility in Participatory Design with special attention to the Latin American context.
