Interactive social media algorithms are developed basically by tracing your web history. In other words, everything you are doing on the web is traced and developed into an algorithm which then specializes in presenting you with product advertisements and even political views that you typically WANT to see. Because these algorithms always steer you toward what you WANT to see rather than what you may NEED to see, they diminish the amount of exposure we have to other peoples points of view and balanced opinions.
For heavy social media users, this tends to increase polarization between people with different points of view. Each side is seeing mostly stories that support their own beliefs and typically this causes people to feel better about their own views while distancing them from the reality of the world around them.
Thus, we are being continuously manipulated on social media and at corporate websites into a manageable herd mentality via behind the scenes, profit and politically motivated digital machinery.
This is what happens to a society when the Almighty Dollar is more important to people than the Almighty God.
