The public sphere in the epoch of the algorithmic hyper-mediation: Fake News, disinformation, misinformation and the commodification of behaviour

The web and concretely social networks are in fast decay. Hitherto considered the place for the flourishing of a new public sphere, space open and decentralised that allowed a massive access to the publishing media, empowering under­dogs and favouring a diverse public discourse. Nowadays, in the epoch of the algorithmic hypermediatization, the web is shifting towards the space of algorithmic bias, and of an amplified and more efficacious politic propaganda, - fos­tered by the resources of micro-targeting and automatic diffusion, as well as, a space polarized by filter bubbles, where extremism resonates. This decay of the public sphere is becoming a threat to democracy that some authors desig­nate as new brutalism. This article exposes the context of this degradation and analyses the role that technological communication mediations play on it, as well as, the diffe­rent solutions proposed y the actors involved in this system from the point of view of posthumanism.
