Less pessimistically, we now have content for a broader diversity of tastes - greater than ever before. As a result, people can choose to watch shows socially with friends, as well as have content just for themselves. And consuming that content can lead to finding new social groups based on shared interests, if they do desire.
I find the diatribe of "things got better, we got worse" so... boring and antisocial? You never magically made friends, you have always had to make them. There are now tools specifically to help you do this, and your pool has become unrestricted to the geographical region of your job. It's easier than ever, it's more likely you're just overwhelmed by the change.
But even that's fine - I made a new friend today while out and about. Just from talkin' like "the good ole days".
