As some have pointed out below, It is more like a new drug that essentially has billions of people prescribed and now addicted to. Its creators (Zuckerberg, Dorsey and Spegiel) have invented the Like, Follow, Heart tools to give us the equivalent of a dopamine hit to manipulate us to stay and continue to get more of them. It then becomes a livelihood to do extreme things just for more attention and followers which dangerously merges social media into the real world and makes it difficult to distinguish on what is real or fake, which is very unhealthy for the mind.
Imagine if FB was a drugs-manufacturer and they are selling drugs called "The Facebook" or "Instagram", etc to you. To use it, just "Post/Like/Follow". Advertisers are also the drug dealers. When we are talking about billions of prescribed users and 100m daily active users, that sounds as if Zuckerberg has become one of the most successful drug kin-pins in history.
If this analogy doesn't sound terrifying, then perhaps its time for some social media therapy then.
