Tool Use by the Humans of Danzhai County

Each section begins with an extract from a fictional scholarly work on Artificial Intelligence; these are a bit dry, but the story itself is well worth reading.

In addition to the post-scarcity plot, where people become free to contribute in the ways suited to their nature (whether socially, technologically, or artistically), there's a good subplot here about people with mental disabilities and the value they provide to society, and of individuals learning to be better people.

Coming back from this fictional world to the real one may break your heart.
