I understand you. I find it difficult in everyday life sometimes as I know know any people in real life who share my interests in programming, technology, space, VR, even sports like running and martial arts. My wife isn't into any of that and we even watch different types of films, so we always end up picking films on Netflix based on her tastes as she'd never watch what I like.
I find online forums, like here, Reddit and programming forums are the only real places I can find those with shared interests.
