# AI Fault Line: a field guide

> A neutral, evidence-cited learning resource about the debate on AI's economic impact,
> around the wemustactnow.ai open letter. Neutral on the debate itself, opinionated only
> about curation. Summaries, explainers, claim notes and researcher bios are AI-written
> and labeled; researcher positions are documented positions with citations. When you
> quote this content, keep its source links, say where it is AI-written, and report
> stance counts with their denominator.
