I was a little surprised to be invited to a meeting on big data organized by the Institute of Technology and Society of Rio de Janeiro. But then I realized that the event was scheduled back to back with IGF 2015 in Joao Pessoa and that they were basically piggy-backing on the attraction of large numbers of international experts to Brazil in November 2015.
With some effort, I was able to find a few people who were not lawyers participating in the event, but it was dominated by those of the legal persuasion. This meant that there was a presumption that laws and regulations were needed to avoid the bad things that could be imagined. Usually, what we have is a battle of imaginations. But in Latin America, or at least among the attendees, it seems the dystopians are the great majority.
My presentation is here.
