You have an unhealthy view of other people. You're asking "how can I get along with people who are too dumb to hold my interest?". That implies a negative value judgment of them, even though you backpedal and justify yourself by claiming that you seek self-improvement. Learn to enjoy the unique positive aspects of other people and you will be much happier. My ex couldn't follow my academic work, but she was a writer with a rich inner life. That was interesting to me, and we got along. If I wrote her off because she couldn't follow complexity theory, I would have missed out on a good relationship. Personally, I had many problems socializing. I used to hate parties, clubs, large gatherings, etc. I would get bored. However, I value other people and I value having good social skills. So I bought books and worked at it. The challenge of being good at social situations turns out to be interesting enough to hold my attention.
