I am not talking about reddit subs, maybe something more niche, even for hobbies outside computing.
The only place where I felt in company of real humans is a couple of niche IRC channels, where someone without fail always asks me how my day is going whenever I join, I am looking for places like that.
Given AI, bots, and desire to make Internet properties collect identification data of all users to make sure they're adults (even though their ISPs already do), I feel like your new, exciting and culture-driver Internet spaces of the future are going to be more like private clubs if trends continue.
They won't be accessible until you physically check in with the admin at a public place, or attending a "Meet-N-Greet" type function. This will make them local-first, and such clubs/forums will have to master the art of developing and networking with other local chapters.
Things operated like this before the Internet, and that's where the real people are probably going to end up back to, because the Internet is becoming as boring and tamed as the capital-intensive corporate-driven phone and TV networks of yesteryear.
Should surveillance increase, I can even see the typical social function of the Internet being nothing more than an events calendar and payment processor, and no other real chat or interaction happening within it.
