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.

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.

I think, by this point, almost everything on YouTube has some ad or another.

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.

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.

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.

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.
