I was just thinking about this the other day. I the not so distant future all books will be “movized” by AI. Plausible future scenario:

Hey (name of magic AI movie app) show me “broken money” by Lyn Alden, narrated by David Attenborough , show graphic charts to illustrate and add extra visual drama. 
Then maybe your book automatically gets some sats as a kick back, David Attenborough get some kick back, the ai app creator gets a few sats, all distributed by some algorithm that relies on public keys like on this app.

Or
Show me Grapes of Wrath, starring Leonard DiCaprio, directed by Martin Scorsese, make rated r and music by rage against the machine
