People are drawn to radical Islam because they feel their traditional ways of life threatened by the influx of KFC and Hollywood movies and the like.

Fifty years ago, the way that we consumed food was revolutionized. We began eating processed foods, and it seemed amazing. And then we woke up many decades later, and we realized that food was engineered to make us fat. And I think that such companies as Google, Facebook, Amazon, Apple are doing the same thing with the stuff that we ingest through our brains. They're attempting to addict us, and they're addicting us on the basis of data.

And I know that sounds outrageous, but it's true. Such monopolies as Google, Facebook, Amazon, Apple are trying to stay with us from the moment that we wake up in the morning until the moment that we go to bed at night. They want to become our personal assistants. They want to become the vehicles to deliver us news, entertainment, to track our health. They want to obey our every beck and call through Amazon Alexa and Google Home.

Most of the time the concept of globalization ends up sounding unnecessarily abstruse - even the name itself sounds clunky and highfalutin. And people discuss it in a way that makes it seem so impersonal. But globalization really is a concrete, fundamental fact in everybody's lives, and you really see that come to life in soccer stadiums.

The New York Times and PBS are gatekeepers of a sort. And they perform that role of gatekeeping with a set of rules and aspirations about where they want to lead their viewers and their readers. They value objective facts, and they attempt to transmit a comprehensive view of the world. And they do have values. And they do lead their viewers and their readers to certain conclusions. But it's different than such monopolies as Apple or Google which are dissecting information into these bits and pieces, which they're then transmitting to people. And it's about clicks.

I don't see tribalism ever really disappearing entirely. I just think that people are almost hardwired to identify as groups. And that sort of group identity always runs the risk of being chauvinistic.
