just because people like the same shit that you do doesn't mean they want to be your friend or you will have any deeper connection than them than the superficial interests involved.
what people are lacking is deep relationships. like emotional connections. not just enjoying being nerdy together. i have been involved in tons of nerdy groups and it never goes beyond the shallow superficial stuff of the activity. like, i don't know about you but talking about shit i have bought or shit i have done isn't really what i'm looking and doesn't really satisfy me emotionally in any significant way.
most of my good friends and relationships came from people I didn't have common interests with, but common values. And my values are rapidly disappearing from the world and people like me are actively shunned by the sycophancy of social media addicted people.
