I hear arguments like this all the time, and it bothers me that such arguments miss that there is something that people like about social media - connecting with people. It clearly is worth it and that's been around since the beginning of the internet in some shape or form be it IRC, forums, usenet, whatever. There's innovations that constitute as modern "social media," like the feed or social search, but the core notion of using the internet to try to connect people is going to be a demand as long as there are people and there is an internet. The best we can possibly do is identify maladaptive innovations and try to provide some alternative, until one is dominant enough that "social media" is as dated as "forums."
