Humans are slowly degrading into braindead zombies.

If not to say that we have already reached that point. We fall for propaganda more easily, we don't think for ourself, we follow social rules and norms without questioning them and we accept everything people say without thinking about it's validity. We're almost like an AI bot who follows the order of other beings but the difference its that we're emotional and unstable. We have come to a point where people don't wanna chase a higher purpose and thus content with the limit society gave us.
