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.

There's this divergence out there between the very small and the very large with the middle disappearing. There is something paradoxical going on where there is this access and we can seek out things on the fringes, but that doesn't describe the overall reality, because the big are bigger than ever.

A big factor is that the enthusiast camp's values are really rooted in Silicon Valley and in these supposedly new business models. But again, I think this such an interesting moment because things like the NSA revelations are really forcing people to recognize the connections between corporate and government surveillance.

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.

Are we on the tail-end of a generation that is enamored with the novelty of these devices and will younger people coming of age be more blasé about them in a healthy way? You look back at the history of any medium and the people who were there when it was developing, whether it was the telegraph or cable television or radio, thought, This is amazing, it's going change everything, or, The human community will finally be able to recognize each other and speak and be one - I mean, some people thought the telegraph or television would usher in world peace.

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.

There's also the issue of tech titans throwing their weight around in Washington and lobbying. There was just a Reuters poll that reported that more than half of Americans are concerned that tech companies are "encroaching too much on their lives." That's pretty major, considering these companies were universally loved not that long ago.
