PROLOGUE

I remember thinking, almost feverishly, about everything this implied beyond the chessboard. If it could do this, what could it not do with a legal, medical, financial, educational, or industrial problem? How many professions, how many processes, how many certainties built over decades were about to be reconfigured from the ground up? It was not an orderly or calm thought. It was more like an avalanche. The same sensation I imagine the first engineer must have felt when he saw a steam engine move a piston and understood, in a fraction of a second, that the world would never be the same again. That was 2022 for me. The compass had turned, and it never went back.

I admit it: it was not the first time I had felt that kind of jolt. There are moments in the life of a technology professional when the ground shifts beneath your feet and you know, with a certainty that needs no external validation, that something fundamental has changed forever. The first of those moments came for me in the year 2000, with the Internet. I remember the feeling perfectly. Suddenly, all the information in the world was beginning to connect: accessible, alive, in motion. Distances collapsed. Intermediaries became less necessary. Business models that had worked for decades began to creak. At first, it was a silent revolution, almost invisible to most people. But for those of us working in technology, it was absolutely clear that this was not a passing trend. It was the beginning of a reconfiguration of civilization.

Then came the second wave: mobile devices. The Internet was no longer something you connected to from a desktop computer in a fixed place. Suddenly, the Internet was you. It lived in your pocket, followed you everywhere, and brought with it new platforms, new economies, and new social behaviors that nobody had fully anticipated. Each of those waves was enormous and transformative. Each created winners and losers on a scale never seen before in modern business history.

But when I compare those moments with what I was seeing in 2022, there is one truly consequential difference. It is not a difference of nature. It is a difference of speed. The Internet took years to penetrate the everyday lives of most people. Smartphones needed roughly a decade to fully redesign the global social and economic fabric. Generative AI, however, did not offer us that courtesy. ChatGPT reached 100 million monthly active users in just two months, according to UBS estimates cited by Reuters, and for a time it was the fastest-growing consumer application ever documented. Two months. That is not an anecdotal figure, nor a number designed to impress in a presentation. It is the clearest signal that this time the rules of the game are radically different. There is no time to watch from the sidelines. There is no maturity cycle slow enough to allow us to adapt later. The window between the moment something appears and the moment it has already changed everything is, right now, smaller than ever. And that realization (the awareness that the clock no longer runs at the rhythm we learned to read) is what drove me to write this book.
