When AI expert and investigative journalist Karen Hao first began covering OpenAI in 2019, she thought they were the good guys.

This small book indeed tells a big story. It is the story of capitalism–of how our market system developed. It is the story of the discipline of economics, and some of the key figures who formed it.

Through his writing, speaking, and teaching, Mollick has become one of the most prominent and provocative explainers of AI.
