A few newsgroups are still reasonably active. I still frequent comp.lang.lisp and comp.lang.ada. Though they now have
tons of spam in them so the interesting parts are somewhere in the garbage. I think most groups have moved to other discussion boards/systems as their primary forum now, and newer groups don't try to create a newsgroup. For instance, I doubt there's a comp.lang.elixir or comp.lang.rust.
As a discussion system, it's pretty much defunct at this point.
