Preface
This book was made with AI. Anthropic's Claude models, working in Claude Code, wrote much of the analysis code and the first draft of the text, and still help update and revise it; Claude Haiku labeled much of the data. In the last days of September I also used OpenAI's Codex, both on this work and to improve the factory's skills. I reviewed every chapter by hand, and the arguments, the conclusions and any errors are mine. Even so, this is a beta edition, and some discrepancies may remain that came from the AI's part in making it. I will keep updating the book; anyone who finds an error can write to me at [email protected].
