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.

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.

There was all this enthusiasm about amateurism and the idea that people could now just make videos in their bedroom, or blog news stories and share it online, and isn't this great? Now we can do it just for the love of it and not try to be professionals, corrupted by careerism.

I try to look at the evolution of these utopian claims. In the late '60s there was an assumption that the wealth generated by industry would be taxed and then put into social programs and it would provide a baseline of stability that would allow people to have the time for self-expression; and that social contract has eroded over the last four decades and now it's every person for themselves.

We like to say the Internet is the ultimate library. But libraries are libraries because people come together and fund them through taxes. Libraries actually exist, all over the country, so why is it such a reach to imagine and to someday build a public institution that has a digital aspect to it? Of course the problem is that libraries and other public services are being defunded and are under attack, so there's a bigger progressive struggle this plays into.

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.

It wasn't that people wanted things for free and asked for advertising to fund it - it's that these companies wanted to amass an audience whose "eyeballs" they could sell, and they gave people things for free to do that. Free services and content has been foisted upon us because there wasn't the will power to explore other options.
