Per this reasoning, producing The Wire or Breaking Bad and most of the "Western Canon" was already unnecessary. Humanity has produced enough written content in antiquity to keep you reading for a lifetime.
Yes, and? My point wasn’t about cultural production, it was about the availability of enormous amounts of excellent curated content. People will make art of various forms without remuneration, even without audience, for the love of creation. Greater rewards will lead to more. But there really is enough great work in antiquity to spend a lifetime on.
