You need to be humbled dude.

Normal people talk about the weather because we're vocal social animals that like to interact, it doesn't all have to be intellectually stimulating. There's always obnoxious disruptive malevolent assholes, but most people, even the ones dummer than you, are good people worth humoring and entertaining. You should be willing to marginalize yourself just a little bit for a functional/pleasant social environment.

You might have a high IQ, some advanced intelligence and knowledge. Maybe you enjoy mentally masturbating yourself by flexing profound well-informed thoughts away from the normies. But that puts you on some pretend high horse. People like you are the problem, not small talk.

There's "dummies" that are more wise than you, making more money, surrounded by more people that love them, helping more people than you'll ever meet. Better functioning humans, that you would consider dumb.

It's not bad to consider people dummer than you. But to pretend they're less capable in a world where social interaction dominates, that makes you foolish and close minded.

You recognizing that you're smarter than average is getting to your head. It matters more how you influence people, how you improve your community, and if you're bored to even talk to them, good luck making a meaningful impact.
