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.

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 think that's been really the key, the idea of trying to harness social capital for selling purposes. That we've let this happen so easily without clearly getting something in exchange is kind of amazing to me.

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.

We already have our phones, but other wearables, and those technologies are going to want to know when you're deciding things and then offer some kind of input subtle or less so on that moment.

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.

I wish more of the web had stayed nonprofit. But the advertising model took over and I think has delivered us to where we are, along with the development of content, which is designed to do nothing else but make you click on it or share it. And I think it's kind of a low goal for content, and I think that's taken us to our current abyss.
