The Scaling Era: An Oral History of AI, 2019–2025

How did we build large language models? How do they think, if they think? What will the world look like if we have billions of AIs that are as smart as humans, or even smarter?

In a series of in-depth interviews with leading AI researchers and company founders—including Anthropic CEO Dario Amodei, DeepMind cofounder Demis Hassabis, OpenAI cofounder Ilya Sutskever, MIRI cofounder Eliezer Yudkowsky, and Meta CEO Mark Zuckerberg—Dwarkesh Patel provides the first comprehensive and contemporary portrait of the technology that is transforming our world.

Drawn from his interviews on the Dwarkesh Podcast, these curated excerpts range from the technical details of how LLMs work to the possibility of an AI takeover or explosive economic growth. Patel’s conversations cut through the noise to explore the topics most compelling to those at the forefront of the field: the power of scaling, the potential for misalignment, the sheer input required for AGI, and the economic and social ramifications of superintelligence. 

The book is also a standalone introduction to the technology. It includes over 170 definitions and visualizations, explanations of technical points made by guests, classic essays on the theme from other writers, and unpublished interviews with Open Philanthropy research analyst Ajeya Cotra and Anthropic cofounder Jared Kaplan. 

The Scaling Era offers readers unprecedented insight into a transformative moment in the development of AI—and a vision of what comes next.
