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.

Look back on the utopian dreams of the previous century, or even the century before that, where people thought machines would ultimately give us a quality of life where our needs would be taken care of so we could all basically be artists together in the evening, after we had fished, hunted, raised cattle - or whatever it was Marx imagined for us.

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?

One connection I see between the work I did on philosophy and my work on technology is that both communities tend to mystify and create an atmosphere of complexity.

I would like people to be more aware of the fact that ultimately we are paying for things, and it's not just as privacy advocates point out that we're paying with our time and our data. We're also paying with money, because the hundreds of billions of dollars spent on advertising is just factored into the cost of the goods that we buy. It's all coming out of our pocket, just in a really roundabout way.

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.
