This presentation argues that we currently live in a world where the algorithms of Facebook, Google, and the other gigants are trying to do their best to deliver content to us that we like.
This has many positive effects as we enjoy seeing stuff that we agree with.
However, there is another side to things. As the evolution of the like algorithms build truths where you never see the other side of the story, we are actually moving further and further away from complete information and understanding of each others differences.
Each node of likeminded likers get their own beliefs confirmed as they only get to see what they like. A situation of misguided intentions appear where everyones good will of creating a frictionless space, leads to a world where we are being led further and further apart.
