As a 1 year nostr user i can relate to this sentiment. Most conversations today are either about crypto or about (building) nostr.

My guess is that the better the network becomes the more that specific content will take a backseat

Same experience here. An overwhelming amount of the content is Bitcoin evangelism, AI slop art, and self-congratulating nostr meta-discussion. All with a heavy-handed libertarian / anarcho-capitalism leaning.

Even the #art is 95% Bitcoin and nostr fan art.
