This book will not talk about the misuse of the Internet, or about the dangers of addiction to the digital world or about the health or psychological problems that long use or the like may cause, as a lot of ink has spilled on such problems. What he will talk about is more important, something related to our "pockets", our money and our wealth, and what this means in terms of restriction of our freedoms, lack of independence, and even changing our thoughts and controlling our cognitive backgrounds, and the resulting digital phenomena that occur before our eyes without us realizing them or understanding their seriousness or danger.
