In the media, traditional media like print, we had boundaries. You know, we had spaces that ads didn't leave. They stayed where they were on the page. They didn't float around over the text. And we're kind of lost on the internet. We don't have any barriers. We have a demand for growth that is insistent.

Markets are born free, yet no sooner are they born than some would-be emperor is forging chains. Paradoxically, it sometimes happens that the only way to preserve freedom is through judicious controls on the exercise of private power. If we believe in liberty, it must be freedom from both private and public coercion.

Google has - at least at this point - maintained the line where it keeps organic results separate from the advertisements. But over time - so in other words, you still get the - there still are honest to goodness results which are based on an algorithm which is based on how important or how many people link to that particular site, so there's that. At the very beginning, there were unobtrusive advertisements on the side that sort of showed up when you typed in certain phrases. Over time, the amount of real estate that those ads take up has increased.

The blessing of the state, implicit or explicit, has been crucial to every twentieth-century information empire.

Movies you pay for - well, sometimes they throw some ads at the beginning now - but generally you pay for ads. And that business model - actually, much more ancient, paying for stuff - is much more straightforward in terms of the incentives of the people who are then giving you the stuff.

Right now it is illegal for a service provider to censor or block a site because they don't like it or to privilege someone who pays them extra money. So it's basically a level playing field. I think it was a great victory. It doesn't solve all the problems of our time, but I think we've gotten a much better place.

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.
