If you have a disease and suddenly start getting ads for cures for that disease and it's an embarrassing disease - all that kind of stuff it just gets into that zone of autonomy or privacy where you feel a sense of freedom to be who you want to be.

Google's AdWords, they allow you to bid on words that people will type into the search engine, and they cost more or less. For example, I think mortgage refinancing can cost - now, it's probably hundreds, maybe thousands of dollars. So, in other words, they are allowing you to bid on what people are going to type, and that is the AdWords program. So you own certain terms, and then your ads show up as opposed to someone else's.

I think Google is the most successful attention merchant - profitable attention merchant in the history of the world, most successful advertising-only based company - most profitable. They started a very idealistic, beautiful company in many ways, but they didn't have a business model.

I am the most concerned that we end up in a situation where your - everything is known about you and so therefore, not only Google, but Google, Facebook, Twitter - the whole set of companies - essentially knows all your weaknesses and therefore how to manipulate you in subtle ways in order to have you do things you might not otherwise do.

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.

I think, by this point, almost everything on YouTube has some ad or another.

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