Can someone propose a test or at least some heuristic to check if you, yourself haven't fallen in that pit? Because this seems like something that would be very easy to diagnose in others, but almost impossible to see in yourself.
More practically: As stated above, if you think you're the most competent person in the room, start looking for other rooms. You don't necessarily have to find new employment to do this—attending meetups and conferences, doing a side project with others, etc. can provide a barometer of where you stand among a wider community.
So looking a bit wider, e.g. "meetups and conferences" if you don't already attend, might help.
Beyond that, look at people working in parallel programming languages - What is the main alternative to the languages that you use daily? And how do the people there do things? In what ways is it better?
