The article is about building network and community by accepting inconvenience.

What will happen is you will meet people, like them, then learn you are absolutely incidental to them, just entertainment.

That's pretty defeatist.

I particularly agree with the points made here:

For one thing, talking with strangers brings a lot of benefits. Research has found that it’s mood boosting, and often more informative than people expect. One study, called “Mistakenly Seeking Solitude,” found that people regularly and incorrectly assume that being alone will make them feel better than interacting with another person.

Avoiding these kinds of interactions is a detriment not only to yourself but also to the society you’re part of. It is often the so-called weak ties in someone’s network—the neighbor down the block you know only casually, the barista you order a latte from once a week—who are the most important in creating a rich sense of community. Because your networks overlap only a little, your weak ties can be a bridge to new connections, or they may know about job openings and social events that you and your close ties wouldn’t have come across on your own. Without weak ties, we wouldn’t have communities, just insular cliques.
