21/m here, I feel much the same. I look at news, I look around me - and all I see is superficial dunces who look like they can't even fathom thinking about 5 years from now, or beyond their own little bubble. No one is interested of talking about science, physics, ideas. It's all about what happened yesterday, or how Becky's getting new clothes, or how they got a high K/D in the latest COD, or other pointless things. But they don't /think/. They don't imagine. Hell - I feel (and act) so different than people in my surroundings that I had (and still have) a reputation for seeming like I'm always high on something, despite me never even touching any drug - I get fascinated by things right under our noses, like cars (thinking about how they work), the human body, the sky (and the depths of space behind it along with all the stars there). I get off tangents because I keep thinking about things (think of it like an IRL wikipedia link game, in my head). I don't pay attention because while they're blabbering about how they're "so going to stuff their faces with pizza pockets this weekend", I'm thinking and creating fictional universes, machine designs (that I put down later should I ever get the means to produce them), mechanism designs (also put down later), game mechanics for the day I have enough me-time to get started on it, and so on. Everyone wants to talk people and events (but not dramatic events like war or new technologies or officials scandals - no, more like how they're doing that festival this summer or how X and Y street is getting torn up for construction again). It seriously sucks.
It seems like you're building yourself up here a bit. How do you know that the people around you aren't also thinking about "important" things? Who decides what's a worthy thing to talk about? It sounds to me like you're writing off those around you as stupid for superficial reasons.
I know how you feel. Sometimes you just feel like no one understands you, that you have this whole universe in your head that other people don't. But the thing that I've realized is that others actually do have their own universes, it's just hard for me to get to those, because I don't connect with that person very well, or we are too different, or just because of circumstance and inconvenience I don't get to know that person well. I think you just have to accept that few people are going to share the exact same universe as you, but that perhaps you can find people to share bits and pieces of that universe to start with. Just wanted to say I understand how you feel!
Thanks - I'm aware that I'm a side show to everyone else - it's just I wish I had someone to share things with.
