The Five Horizons: From Agent to Autonomous Economy

Every few years, the way people work with machines changes. What people hand to a machine has moved from a query, to a message, to a task. Now it is a role. By October 2026, the two leading AI vendors both offered an AI that keeps working on its own while you are away, and open-source tools let people run one on their own computers.¹²³ An AI Worker is an AI that holds that role. You assign, govern and manage it, much like anyone who holds a role on your team.

This book is about that change, and about where it leads. The five horizons below are the steps in that change, from the AI Agent era to a possible autonomous economy. They show which parts of the book prepare you for each step. The first edition covered Horizon 0, the AI Agent era, and this book keeps its principles. You start at Horizon 1, the AI Worker era, which has just begun.

The five horizons

This is the book's outlook as of October 2026. Read the figure from the bottom up. The dates are indicative, which means they are not exact. The future horizons are forecasts, and Horizon 4 is only a possible future. The horizons also overlap. Parts V to VII already prepare you for Horizons 2 and 3. Early signs of Horizon 2 are already visible. One vendor is testing ready-made AI Workers for companies, each with its own identity and system access for one role.¹

How the human role changes

The ladder below shows the same change from the human side. Each level of the ladder is called a rung. At each rung, what people do is different. The four rungs at the bottom exist today, and the Preface calls them the ladder of interaction. The three above them are forecasts.

Where this book starts

Managing one AI Worker well is the foundation for coordinating a workforce. A country needs people and companies with these skills before it can produce and export AI work. So this book starts with one AI Worker, and how to manage it well.

Across every horizon, humans set purpose, define authority, and remain accountable.

The Preface comes next. It shows this change in one person's work, and it defines the main terms used here.
