Have you ever woken up at 4 in the morning to buy sneakers? Me neither, until that night of a family vacation when I ran into my 12-year-old nephew who was half asleep in front of screens. I felt sorry for him, I tried to help him. And I discovered the technologies that make us addicted and almost mentally retarded. To understand, I went to Silicon Valley for some latte macchiato with the so-called cool guys who designed these applications which make us their slaves.
