Well no, we need billions of human-level AIs who are experiencing a world as rich and various as the world that the billions of humans inhabit.

Once we've got the first, making a billion is easy.

That said… are content creators collectively (all media, film and books as well as web) a thin tail or a fat tail?

I could easily believe most of the actual culture comes from 10k-100k people today, even if there's, IDK, ten million YouTubers or something (I have a YouTube channel, something like 14 k views over 14 years, this isn't "culturally relevant" scale, and even if it had been most of those views are for algorithmically generated music from 2010 that's a literal Markov chain).

Maybe we could print out knowledge on dead trees and store them somewhere, perhaps make it publically available? (stolen joke, not mine).
