Source
Expertise is a high level of skill or knowledge in a particular domain, typically developed through extended practice and exposure to varied cases.
Interpretation
This project is interested in the pipeline that produces expertise — what kinds of tasks and repetition build it — and in what happens to that pipeline when its early, formative tasks are delegated away.
Caution
Expertise is not the same as confidence or credentials; conflating them is a mistake this project tries to avoid.
