AI creates fiction that sometimes intersects with reality, in the same way that Legends & Lattes has a few real-world things like coffee shops and lattes, but the things like orcs, ratkin, succubi, and magic that comprise the rest of the details are still currently fiction.
People just need to learn to assume LLMs are always writing fiction with a handful of details borrowed from real life.
And that's honestly a good thing. We don't need Twitter clones, because as much as people remember the Twitter of yore fondly, the people in charge made some really terrible decisions for their users, and a lot of people have forgotten that.
Mastodon is and should always be distinct from the Twitter-likes; if it starts to be a little too similar, then it's probably lost its way.
