Introduction

This book was written with AI assistance, used to help transcribe, translate, structure, and clarify the author’s ideas.

In November 2022, OpenAI released ChatGPT as a research preview. It reached a million users in five days, and by early 2026 it had 900 million weekly active users. Google’s Gemini, Anthropic’s Claude and a crowd of smaller rivals grew alongside it, and within three years, talking to a machine in plain language and getting something useful back went from a curiosity to a daily habit for a large part of the connected world. Few consumer technologies have ever spread this fast.

That adoption is the starting point of everything that follows. The personal agent — broadly speaking an AI agent with a persistent memory, just like Claude or ChatGPT — is already part of ordinary life, consulted for questions that used to go to a search engine, a colleague or a friend, and it has already begun to act on our behalf: agents now write and ship code, fill in forms, compare offers, book travel, sort through inboxes and build small pages and apps for the people who use them. For now these uses remain concentrated among early adopters and in a handful of domains. It is their generalisation, the moment sending an agent to act on our behalf becomes as ordinary as clicking a link, that will set in motion the shift this book attempts to describe.

When a new technology emerges, most people first imagine how it can solve the problems they already have. They see how it can make existing tasks faster, cheaper, smoother and more efficient. What they rarely see is the new world contained in the seed: the new uses and new structures that will inevitably, almost mechanically, arise from the new status quo.

This is what is happening with AI today. Most discussions still frame it as an enhancement layer: a better search box, a smarter assistant, a more fluid interface. That is not wrong. It is simply short-sighted. What is now underway is not just a productivity gain. It is a structural shift, and it should be described as such.

We are moving from a world where humans engage with digital systems directly to one where they increasingly operate through agents that remember, filter, compare, monitor and act on their behalf. Human presence in the digital world is beginning to take a new form: delegated and represented.

This is the Agentic Shift: a practical redistribution of action, attention, coordination and representation that will affect our lives and our societies at many levels. A new paradigm is emerging and consolidating right in front of us. A tipping point that I believe is worth our collective attention.

The following chapters are my attempt to map this new territory as it evolves, to follow the trajectories already in motion and see where they lead, where they cross, the new spaces they open and the new questions they raise. This map is not exhaustive: the field is an ever-moving ocean, and it is only meant to be a high-level view of the territory it sets out to explore.
