Of course we are brilliant creative geniuses! I'm biased of course.
I don't know that we are necessarily "smarter", but I think we are more complex, sensitive, and perceptive than some other types of people.
I can't speak for others, but, intellectually, I'm generally one of the sharper tools in the shed. Creative writing is a passion of mine. I tend to be insightful because I've laid awake many nights contemplating the meaning of life. Haha. Like you, I have little tolerance for superficial people and meaningless conversations. I find that kind of socialization exhausting, so I mostly avoid it.
If you think about it, the Bipolar diagnosis itself is complex. It stands to reason that people who receive the diagnosis have many fascinating layers.
I try to accept that being Bipolar is an "illness". And when I'm in a depressive episode, it's easy to embrace it. But it really isn't all bad. All that childhood trauma, the dysfunctional coping mechanisms, and rapid cycling makes us pretty dynamic creatures.
