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

History shows a typical progression of information technologies: from somebody's hobby to somebody's industry; from jury-rigged contraption to slick production marvel; from a freely accessible channel to one strictly controlled by a single corporation or cartel-from open to closed system.

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?

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.

Starting with radio, starting with television, we got used to this idea of stuff being free as long as you just watch a few ads.

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.
