I want to say, however, one thing our media in America has done which didn't happen in other totalitarian states is it has very effectively stood up to Donald Trump who has obvious fascist tendencies and his - who's a temptation like all authoritarian figures to try to crush the media or make it obey him. As that - the media has, in fact, stood up to him and has refused to bow out or cower.

One thing I'll say about Hitler that many people don't realize - and I don't mean to besmirch the industry - but he did get his start, not only as an artist, but as an advertising man writing art for advertisements.

When you decide to like something, I mean, you may feel you're sort of innocently putting out your preferences, but actually you're delivering something of enormous value, which is indicating that, you know, you'd essentially like to be advertised to by this company.

What's so interesting about the internet - I keep saying this - is the web has gotten worse over the last five years as opposed to better.

The Internet, you know, 10 or 15 years ago sort of felt like the wild West. You could go out there and do anything and search for things, and, you know, find out about stuff. Now always in the back of my mind, you know, whether it's email or whatever else, it's like, well, is this going to show up somewhere? Is someone going to keep track of this and, you know, know I was searching for - maybe it's an embarrassing disease, maybe it's a weird hobby?

Hitler had this understanding that you speak to people's deepest, darkest emotions and give them voice that can be incredibly effective.

All business models have something challenging about them, but the problem with the attention merchant business model they have is they need to keep increasing the amount of ads they deliver to people and therefore make their product worse.
