There's always going to be merchants who need to get their message out, but things have gone way too far.

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.

There's always going to be a tradeoff between trolling and anonymity, and I guess that's the way life will be. And you can manage it, but you can't cure it.

I'm afraid when too many people know too much about you, it actually makes us all a lot more boring because you're afraid to express yourself.

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 do think the best thing for companies like Google and Facebook, if they are afraid of this ethical trap of advertising, is they should start letting people pay who want to pay and avoid some of the advertising.

Advertising just keeps getting heavier and heavier and heavier. It doesn't have any natural limit, and we haven't found the place for the limit. And I think it's really important, therefore, that some of the revolts that are undergoing right now, you know, whether it's ad blockers or other things, are people trying to set some lines so that we say, you know, this far but no further. And this is where it ends.
