Platforms, algorithms and AI: Issues and hypotheses in the mediatization perspective

José Luiz Braga 340 for them to permeate with neighboring compositions. I believe that this reasonably defines what a “bubble formation” is. The risk of social bubbles is also twofold: they become impermeable to their surroundings; and they promote a strong reduction in the group’s internal diversity. The concerns that were raised for a while in the 20th century about the predominance of television over writing seem to have been reversed. At the time, it was a source of concern that given the pregnance of television channels – which were not very diversified and had a wide reach – they would lead to a generalized predominance of single-mindedness, associated with a superficial perception of things – all of society happily futile and irresponsible3, in a worrying unison.Now, conversely, we no longer have the risk of single-mindedness or even the fluctuating perception of futility. The inhabitants of virtual bubbles, in blind and intense adherence to the stances of their “separate reality”, generate a radical dispersion, incapable of joint action and even of simple thoughtful debate with “external” sectors and ideas, for broad social objectives that would lead them to the construction of a complex social reality and ensuring of effective composite diversity. Without this pursuit of compositions of diversity, what we have is a paradoxical situation of multiple “unique” thoughts, isolated and rejecting each other. The challenge is to avoid this closed “corporate” po- tential of digital algorithms, resulting from a (non-transparent) selection of only a few preferences of the participants – which are thus reinforced, deforming positions. How can we ensure more open compositions with renewing, diversifying, and farreaching dimensions? e) Imbalance in the mutual incidence between individual actions and social patterns We pointed out in the second section of this paper the diversity of the human species as a quality that adapts to differ- ent circumstances. The way in which social praxis reinforces di3 We inevitably remember Tom Zé’s sarcastic and fierce song from the 1960s, “happiness will spread throughout mankind”; and, in the same period, the mov- ie Fahrenheit 451, directed by François Truffaut.
