Neal Stephenson "The Diamond Age: Or, A Young Lady's Illustrated Primer"
It's a 25 year old book but slight spoiler, it's about what happens when this book made for a rich billionaire's child falls into the hands of a poor child. Among many interesting ideas, the book has its own source of funding (think, crypto) and uses that to hire actors (like zoom with full on mo-cap) to bring to life the characters in the story. IIRc, the lessons/dialog are all written but the actors can bring them to life and ad-lib, and one actor in particular ends up being the remote mother for this child.
Oh, another bonus part of the story I remember to give you an incentive to read it, there's a multi-page digression about how turing machines work retold as a fantasy allegory with like, castle bridges, chain links and trolls.
