A lack of boring friends, maybe. And sure, maybe there's few actually interesting people out there, so that means a lack of friends in general, but why you do need people? It's ok to be alone until you meet people who are genuinely interesting. Even better when applied to dating: it's perfectly OK to be single until you meet someone actually worth your time, instead of wasting effort on someone you don't really enjoy just so you're not alone. When you don't need other people around, the quality of people you do keep around goes up exponentially, as only the people you really
want around will be left.
In other words, if these people are so uninteresting, why are you interested in them? And if you really are interested in them, why do you need to
pretend to be interested in them?
Alternatively, if you for some reason have to pay attention to someone you find boring: find the most interesting part of whatever uninteresting drivel they're bleating and ask questions about that. Find the most interesting part of their response to that, and keep drilling in deeper until you find something they have to talk about which is actually interesting. Then follow the connections from everything else they say back to that. That's the approach I always took to class lectures: whatever the subject, there's bound to be something to catch my interest buried somewhere in there, so I'd just find that and then focus on how everything else in the subject connects to that.
