I would agree to what you say about social media in general. But you know, when you look at it in terms of a large average of people, it is mostly stupidity that prevails on social media. Especially with the selfie trend, the attention seeking attitude and over the past few years, the rise of fake news and the inability of people to sift between facts and nonsense. But social media also has a lot of intelligent people on it. The reason we don't see them often is because they are too busy to be posting or doing stupid things.

The problem with most social media is that it doesn't demand quality, and you are basically interacting with friends, and most of them will be either like you. So stupidity is followed by more stupidity.

However steemit has its limitations example are those who post a single pictures of cat, bees , flower, birds, house etc without any explanatory notes. - This will be a trend that will continue. However, most of these users will not be around for long because of Steemit's culture.
