Where is social media headed?

That would be catastrophic. The world runs on bullshit.

Perhaps that requires some clarification to avoid cynicism:

Bullshit is information presented without regard to truth. Therefore bullshit in a Venn diagram contains both all truth and all non-truth. And that allows the premises:

There is some truth in all statements - ie In God We Trust

There is some non-truth in all statements - ie In God We Trust

In God We Trust is obvious bullshit, but it sells well to a large media audience.
