The social media algorithm creates special and unique "Plato digital caves" for each of us, according to what it learns from us. He knows how we think, our affinities (religious, political, sexual, etc), our tastes (musical, family, couple, food, etc.) what offends or pleases us, etc.
The algorithm will keep recommending you the same content over and over again keeping you in the "shadows" regardless of whether the content is good or bad / true or false, just to keep your attention caught. This practice can not only cause collective ignorance, but it can generate polarized and even extremist thoughts, because it does not show people information beyond their way of thinking, this in the wrong hands can even implant ideas and beliefs in the collective thinking.
