The algorithmic strategies of the "post-truth" era came to unconfigure politics and are undermining the foundations of the old democracies. In addition, the new ‘clickbait’ dynamics are aggravating the already fragile positioning of the journalistic phenomenon in the contemporary world.This algorithmic turn, which came to politics, news and social interaction, is evolving to a fathomless dimension, not only because it constituted the algorithm in gatekeeper but also because it created propaganda machines specializing in social engineering, in automating political behavior and in emotional chains, manipulating opinion and creating new spirals of silence. Culture, politics and communication face these new gulfs. In this paper we will try to analyze this vertigo, this technologization and dystopia of mediation and knowledge, the new propaganda, armed now by Artificial Intelligence, in which digital platforms and their algorithms do not yet control the processes of interaction and communication, although they clearly monitor and track us, bringing the democratic experience back to more complex levels of historical and political regression.
