I grew up on a island where there was maybe one or two other people who knew computers enough to know programming as a thing existed as a concept, but similarly to you, absolutely nothing else, and it gets very lonely and outright boring after a while.
I solved this (accidentally) by moving to another area, but isn't possible for everyone, then the closest you can get to that would be to bring people closer to where you are instead, or start up something small and reoccurring :)
I stopped going, because the “circle of avoidance” around me makes me self-conscious.
The ageism in New York, is even worse than in Silicon Valley.
No one makes eye contact, and no one looks at me. I find it extremely difficult to start conversations, and I'm a fairly gregarious chap. There's usually a space around me, about a meter wide; even when it's crowded.
The good news is, I rarely have trouble finding a seat.
As much as I'd like to judge, I had a little bit of that 'elder avoidance' in my 20s, and I look back and cringe at how stupid I was.
I'm old enough now to know that 'my people' can't be determined by things I can judge easily by looks or short interactions. I'm going to hope they get it at some point.
