I think Google is the most successful attention merchant - profitable attention merchant in the history of the world, most successful advertising-only based company - most profitable. They started a very idealistic, beautiful company in many ways, but they didn't have a business model.

Markets are born free, yet no sooner are they born than some would-be emperor is forging chains. Paradoxically, it sometimes happens that the only way to preserve freedom is through judicious controls on the exercise of private power. If we believe in liberty, it must be freedom from both private and public coercion.

I think you spend 50 percent of your mental energy trying to defeat ad systems.

I think, year in, year out, Google is starting to get worse instead of better. I think this is happening to a lot of the web companies, is as their demand to increase the payload they deliver in ads increases, they end up degrading and corrupting their own services. And you can see it with Google Maps, you can see it with Google Directions, where somehow Uber is, you know, always one of the options. And it's becoming exactly what they said was what they never wanted, which is a pay-for service where the highest bidder gets the best results.

The breakup of Bell laid the foundation for every important communications revolution since the 1980s onward. There was no way of knowing that thirty years on we would have an Internet, handheld computers, and social networking, but it is hard to imagine their coming when they did, had the company that bured the answering machine remained intact.

I don't think anyone at Google feels happy about it, but they've been in some sense, you know, enslaved to their business model, and so they have to satisfy their advertisers.

Every time you click on a like button on another site, you've told Facebook that you're doing that. And so therefore advertisers know who their fan base is.
