Early on, America took one path and went down the advertising road, and in the UK they founded the BBC and developed a different kind of public broadcasting. There was a point where TV was so beholden to commercial interest that people - civil society - actually rose up and said, "This is ridiculous: we have our soap-selling soap operas, cigarette-sponsored news broadcast; we have our rigged quiz shows - let's put some checks and balances here."

It's very complicated. There's been this broader mechanism, an industry, which wants people to use free services, from the old days of advertising-supported papers and magazines, to ad-supported free television.

One thing I point out is, a lot of people tooting the horn of amateurism, actually, these people were professionals. Some are professors who are employed full time. Others are marketers or business consultants.

It's the same thing in a way with privacy. You can say "I'm not doing anything wrong, therefore this doesn't concern me," but what does it mean about our society if we're all being watched and recorded? The personal experience - negotiating this as individuals - doesn't describe the social reality and the broader social costs.

We've been criticizing these superficial aspects, like whether we are all more distracted. We really need to articulate a defense, a critique, that merges awareness of the technology with a more traditional, progressive, left-wing critique of the market.

My point, though, is that if lines have indeed shifted, it's not so much that the younger generation just doesn't care, it's that we have ceded more and more of our public life over to the private sector. If you grow up with advertising at school, you have come of age in a sold-out world.

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.
