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.

What's so interesting about the internet - I keep saying this - is the web has gotten worse over the last five years as opposed to better.

Wikipedia, a nonprofit, is an enormously popular website but has managed to operate without advertising. And, you know, maybe it's a little simpler than Google and YouTube, but it does show there's another way.

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.

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.

If we generally like the way things are now, we must also ask whether our current situation is really so different from the open ages of radio, film, or the telephone. Might it not also have seemed in those times that the orgy of limitless entrepreneurism would never end? The point is that we are near the high end of a pendulum arc that, so far, has aways begun to swing in the opposite direction -toward greater integration and centralization- with a force that can seem inexorable.

Google has you at a very specific mental state that is, looking for something. And what they've always been able to say is, we deliver your message at the exact time someone is, say, looking for fishing hooks or looking for marriage counseling or looking for a lawyer for a particular problem. And here we have our customers telling you what is in their heart and soul. It's something that, you know, advertisers have wanted for decades.
