But what kind of art? There are some great slam poetry events. What about interpretive dance? What about tea ceremonies? What about abstract monotone painting done with watercolors? What about painting Warhammer miniatures?
It's a massive field. So is programming. It's possible to meet with a person who also loves programming, but if you like working on networking backends and the other person really just loves writing shaders, programming alone is hard to find a common ground. It's like a person who loves slam poetry talking about their hobby with someone who's only interested in Warhammer. When they find a common topic to talk about, it'll probably be anything but slam poetry and Warhammer. It'll be a different hobby, like surfing or making homebrew beers.
What I'm saying is, expand your interests. Try some things you've never even imagined being interested in before. You'll be surprised what you enjoy.
