It just seems unusual that a lot of people like the same thing.
The same thing happens with non-AI music too. Artists you've never heard of have songs that suddenly become viral.
Yeah, there's this dude, haven't heard anything from him in a long time, but it was somebody that I used to know...
That's true, but I've noticed that AI text content is very prompter-focused. Someone once described them as dreams - more meaningful to the dreamer than to anyone who has to listen to them narrated. Perhaps it's just inherent to the fact that textual content is rarely viral at that length. It's a base-rate issue.
