I feel your pain.

I also have some non-popular interests that a really wish that people i know would be mor interested.

But the truth is that most of the people dont like to talk about economics, philosophy, politics, whats behind an history, cryptos.

And there is not much we can do about that.

At most, we can start to talking about the topic, and watch If someone get interested of excited about it. If not, move on. Eventually you Will find people that want to talk about this.

Think about yourself. You also have a lot of topics that you dont care much, but other people love to talk about. Human nature.

Nowdays que have the interwebs, where there is always a place to find people around the world that share the same interests.
