From acclaimed Financial Times columnist and CNN analyst, a penetrating indictment of how today's biggest tech companies are hijacking our data, our livelihoods, and our minds.

"Don't be evil" was enshrined as Google's corporate mantra back in its early days, when the company's cheerful logo still conveyed the idealistic spirit of the enterprise, and industry as a whole. Unfortunately, it's been quite a while since Google, or the majority of the Big Tech companies, lived up to this founding philosophy.

And yet that quaint slogan--which has since been quietly but deliberately abandoned by Google leadership--reminds us that giants like Google, Facebook, Amazon, and Apple weren't always the cash-printing corporate leviathans they have become today. In fact, they were born out of a starry-eyed vision for a utopian future in which technology would inevitably make the world better, safer, and more prosperous, one in which the internet would be a grand connective force, uniting us in one global village while leveling the playing field for all.

How long ago that all seems. Because in the span of the past two decades, writes FT columnist Rana Foroohar, Big Tech lost its way--and its soul. Through her skilled reporting and unparalleled access--won through nearly 30 years covering business and technology--Foroohar tells the story of how giddy idealism turned to greed, how a world where "information wants to be free" became one in which we are the product being monetized, how the geeks tinkering with motherboards in their basements grew to be arrogant billionaires monopolizing the lion's share of the economy, and how the "democratized" internet we were promised came threaten the very fabric of our democracy.

RANA FOROOHAR is global business columnist and associate editor for the Financial Times. She is also CNN's global economic analyst. Previously, Foroohar was the assistant managing editor in charge of business and economics at Time, as well as the magazine's economic columnist. She also spent 13 years at Newsweek, as an economic and foreign affairs editor and a foreign correspondent covering Europe and the Middle East. During that time, she was awarded the German Marshall Fund's Peter R. Weitz Prize for transatlantic reporting. She has also received awards and fellowships from institutions such as the Johns Hopkins School of Advanced International Studies and the East-West Center. She is a life member of the Council on Foreign Relations.
