Actually, nostr:npub1995y964wmxl94crx3ksfley24szjr390skdd237ex9z7ttp5c9lqld8vtf , now that I think of it, I'm probably seeing the same effect. It's just that computer nerds, religious nerds, rural nerds, political nerds, dietary nerds, etc. have more incentive to meet up and organize. And, since nerds are a type of personality, rather than a particular topic, those nerds can occupy multiple nerd-spheres.
I was actually thinking about this, yesterday, as we sat down with the CSU guys from our village and I noticed that the four tables they used to occupy are now two tables and everyone was our age or younger and most of them are engineers or into techy stuff as side-gigs or hobbies. And our daughters are all into vegan cooking, apparently. 😂
Nerds are taking over what is left of society, seems like.
