Whatever cool people there were have either died or saw the writing on the wall as IRC slowly faded into obscurity with the introduction of better (debatable) chat systems, especially these days with things like Discord or Slack that do every IRC does in some capacity and more, perhaps most importantly simply making chat accessible in a safe way to less technically savvy users. That genie is kinda out of the bottle, so getting anyone aside from grumpy old guard to use IRC versus the modern alternatives is pretty much impossible. As a result, and aside from the bots doing things like letting me play IdleRPG or whatever, you're more likely to encounter people like me who don't feel like we fit in anywhere or conspiracy theorists, returning to IRC the way Romero's zombies wandered to the shopping mall because they had a vague memory of it from a former life.
Just join Libera's #politics. Full-on leftist politics where another opinion is not allowed

And, well, I'll just open the radio playlist with mocp.
Just a lot of ghost towns in between them.
On the ghosts towns, with FIDO/DOVE you get far less posts, but every group has some content. With Usenet, you either have loaded technical groups (and some less tech bound ones such as misc.internet.discuss) plus some niche hobbies (chess, classical music...) except modern PC gaming. The rest, as you said... shadows from better places.
For postmodern bullshiters, hauntology it's never a thing on open services. There's always some people having fun there. Former propietary or web bound services are dead, forgotten and lost. Such as MySpace, Digg, unpatched MSN-AOL-ICQ, the Spanish slashdot clone (Barrapunto), Libertonia (es.comp.os.linux related slashdot clone) and so on.
