How YouTube Radicalized Brazil – The New York Times

“NITERÓI, Brazil — When Matheus Dominguez was 16, YouTube recommended a video that changed his life.

He was in a band in Niterói, a beach-ringed city in Brazil, and practiced guitar by watching tutorials online.

YouTube had recently installed a powerful new artificial intelligence system that learned from user behavior and paired videos with recommendations for others. One day, it directed him to an amateur guitar teacher named Nando Moura, who had gained a wide following by posting videos about heavy metal, video games and, most of all, politics.

In colorful and paranoid far-right rants, Mr. Moura accused feminists, teachers and mainstream politicians of waging vast conspiracies. Mr. Dominguez was hooked.

As his time on the site grew, YouTube recommended videos from other far-right figures. One was a lawmaker named Jair Bolsonaro, then a marginal figure in national politics — but a star in YouTube’s far-right community in Brazil, where the platform has become more widely watched than all but one TV channel.”

David Lindsay:  When Elizabeth Warren included Google in her list of major Social Media and Tech companies that should be broken up and heavily regulated, I thought she had gone overboard. It turns out, she was right, and I was clueless as to what a nightmarish monster parts of Google, such as Youtube, have become, aiding and abetting the rise of facists and extreme right wingers around the world. I now join Elizabeth Warren, that Google is on the list of oversized and dangerous monoliths that have to be broken up and carefully regulated to protect democratic and open market values.
