When the Internet appeared in our lives, millions of people on the planet thought that it would open up a world of colossal opportunities for everyone and that this was the greatest civilizational shift since the Industrial Revolution... However, what do we know about the dark side of the Internet? Andrew Keen undertook to open the eyes of humanity, who in Silicon Valley was called the Antichrist for his harsh criticism of plutocrats like Mark Zuckerberg, who earn untold wealth by using the personal data of ordinary users. Keane tells how the owners of Google, Facebook, Twitter, Instagram, and other “digital giants,” acting on the “Winner Takes All” principle, are exacerbating unemployment and economic inequality, and how Internet business has given rise to an entire industry for mining and processing our personal data. A detailed reconstruction of the technological and economic picture of the Internet will be of interest to anyone who wants to enjoy its benefits with minimal damage to their own security.
