The realization that "normal" people don't care and will never care was the saddest for me. There are so few people who care. We're essentially irrelevant in the grand scheme of things. We have no leverage.
Different people care about different things (beyond near term well being). We have no ability to be deeply involved in million different topics, but most of us care about several. And random couple of people may have no intersection and could symmetrically see each other as a "useless normie".
That's, uhm, normal and why groups form by interests, from cooking to hiking to reading to hackerspaces to rocketry. I see it as neither bad nor sad. My 2c.
What exactly are you sad about? You're only just realizing highly technical knowledge makes your opinions a minority?
DUH.
Guess what? That same knowledge gives you agency. With LLMs now, even more so. Want something? Build it (or have claude build it)
Why are you being a defeatist over something you can't control that was always the case? Nothing has changed.
When I was younger and I heard the saying along the lines of "struggling against the indifference of the universe" I didn't realize at the time it included people too.
