One thing that struck me about going to those tech conferences was all the enthusiasm for free culture, and remixing, and social media, but people's greatest ambition was to be sponsored by Chipotle or something equivalent to that. It was this weird mix of collaborative, utopian claims and this total acquiescence to commercial imperatives.

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.

The point is, this is what happens when advertising and data collection is the dominant business mode. We are encouraged to be compulsive. It's not that we're terrible addicts who need to go to an AA meeting and get off our gadgets.

I'm interested in the way the whole cultural landscape can shift over time. Okay, this will seem like a silly example, but look at the whole discourse around "selling out," a concept people say is irrelevant because there's no more distinction between mainstream and underground, inside and outside (which I don't really believe, but that's another issue).

All this stuff - about the materiality of the network, what it's made of, and how it works - should be part of a basic media literacy, because we depend on this technology for more and more aspects of our day-to-day lives.

ulturally, we are definitely seeing people being to ask hard questions. There's been a major shift over the last year. The NSA revelations played a big part but there are all sorts of other issues too, like inequality and gentrification in the Bay Area, and labor abuses everywhere from Amazon's warehouse, to Apple's factories, to start-ups like Uber and TaskRabbit.

The point is, there's this new sense of skepticism and questioning toward tech, even if it is pretty inchoate. What I hope the book helps to do is help people clarify what is amiss, by presenting a critique that is grounded in economics.
