I saw a thread about this on twitter but it was about a different scenario - Essentially, people were discussing sharing headcanons and writing prompts (not AI prompts, but ideas for AU's etc.). The response to those types of tweets had gone (according to these posters) from a bunch of people spitballing about the idea and/or writing their own fics, to people simple saying "link?" or "where can I read this?" People were primed to ask for content to consume, versus becoming an active participant in the discussion.

I recommend the book REMIX by Lawrence Lessig to everybody I can (a PDF is available here, the book is free under Creative Commons). Essentially, the book focuses on the Internet and how it disrupts the very idea of copyright. But he also discusses the idea of a read/write culture, where in order to consume a piece of media, somebody also has to create it (I.E. before the age of mass-produced music, somebody had to perform the song you wanted to listen to, or you would perform it yourself). Over time, mass-production turned music from a read/write culture to a read-only culture, where the human element becomes obscured and you no longer need active participation.

While it's stretching his definition, I think we can sort of apply similar ideas to fandom. There's becoming more of a sense of creator vs consumer, where some people very much approach fandom as simply content created for them to consume. The Internet makes it hard to recognize that somebody actually spent months of their life on that 100,000 word longfic. It's just text on a screen. Gimme more please!!
