Technology and television didn't dictate one path or the other - it was civil society and public policy intervening in creating alternative funding models. So I think that's one of the questions for our time: do we want to intervene in this model or completely acquiesce and leave it to the unfettered, not-actually-that-free market? Neither path is inevitable.

What we need to do is take that inchoate sense that something isn't right and give it a structural component and the sense that things can be another way.

think there's a culture of Silicon Valley that seems to have the attitude that you can have it both ways, that you can be an insurgent but also, ultimately, it's paid for by advertising, when in fact advertising is totally retrograde. Now that's an industry we should be disrupting, and maybe you disrupt it by funding public media. None of this is technological destiny; there are only social choices.

And of course the things that get the most attention online tend to be similar to those that succeeded under the old model.

Technology isn't simply addictive - it's addictive because it's a servant to business incentives. There are huge departments in these companies that are devoted to this and staffed by incredibly talented people who have skills that could be put to socially beneficial projects but who are now trying to find out how to make you click and how to maximize your time on a certain site, or encourage teenagers to "friend" more products and constantly engage with them.

I think that overall, ultimately the impact of advertisers calling the shots is a more cloying, complacent culture. For example, it was just announced that Unilever is branding environmental content at The Guardian. How radical or pointed can that content be?

Whether it's a professional, academic keeping people out by using certain mystifying language, or technologists presenting their work as incredibly complicated, no one can understand it (especially not "moms," who are always invoked as the ultimate know-nothings, which is incredibly insulting to a whole lot of people).
