With a letter, which the creator of Facebook, names as “manifesto” the social network decides to filter its content.   Facebook's goal is to free every user - as much as possible- from fake news, content that promotes racism, exposes the naked or insults people and ideologies. There have been many cases where Facebook removed content that had historical value because it depicted naked children, while in other cases, messages with hate speech or racist content circulated freely within it.   For that reason, ο Mark Zuckerberg, found time to write a letter 6.000 words approx, in which he describes a new era of Facebook's algorithms, posing, in fact, very high bar, as he considers his vision of connecting the world through the social network to come closer to completion, combating all phenomena that cause trouble and unrest.   Ο Mr. Facebook has very high goals, but Facebook users continue to be in dire need of better tools to filter the content they receive in their daily news feed. For Facebook the solution to a more connected world lies in the social network's best operating algorithms, which are expected to be endowed with artificial intelligence.
