What if intelligence was just a resource? What if thinking and reasoning were no longer rare advantages-but abundant, on-demand utilities available to everyone? What happens when intelligence itself becomes as cheap, reliable, and ever-present as electricity? That moment has arrived. Unmetered intelligence-AI's ability to deliver limitless cognitive power at near-zero cost-is reshaping the foundations of work, education, science, and art. It's the greatest expansion of human capability in history. In The Next RenAIssance, AI pioneer Zack Kass reveals how this new abundance can unlock a golden age of human flourishing-if we have the wisdom to use it well. Drawing on sixteen years at the frontier of AI, including his time at OpenAI during the launch of ChatGPT, Kass offers a profound and non-obvious roadmap for a world where intelligence is infinite, and humans are forced to explore what comes next. This is not a story about machines replacing us, or even about technology. It's a story about what becomes possible, for better or worse, when human potential is unbound.
