very structures of power, it's interesting, some would say ironic that mark zuckerberg has chosen it, because he is one of those new power structures. >> right. and what the book argues is that there's no denying that there are very centers of power. there could be president obama, and the pentagon. those are centers of power here. what i argue in the book is that power is becoming more ephemeral. and those who have power are more constrained in how they can use it. they have more limits on what three can do with it. >> i can see that argument certainly holds great water with a president, a pentagon, a vatican, but when you're talking about zuckerberg, such as facebook and social media, do you see the same constraints?
