You have to think back to the '90s. The computer was this terrible-looking thing that was trying to compete with the television. And it was this idea of email and chat rooms and this kind of stuff that first people - got people there.

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.

The best antidote to the disruptive power of innovation is overregulation.

I'm kind of calling for a - I'm not the only one - you know, a revolution of some kind where we try to take back the web or start something new because, you know, the dominant medium of our time is in a desperate state and it doesn't have to be like that.

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.

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.

In fact, the big steps forward for advertising, especially after World War I were when government just began employing the tools of advertising for its own purposes to get people to join the army and other things.
