Glenn Greenwald:

For anyone who supports the general Obama "war on terror" approach or specifically his claimed power to target even US citizens for execution without charges, it's impossible to object to Graham's arguments on principled or theoretical grounds. Once you endorse the "whole-globe-is-a-battlefield" theory, then there's no principled way to exclude US soil.

Bruce Schneier:

This is ubiquitous surveillance: All of us being watched, all the time, and that data being stored forever. This is what a surveillance state looks like, and it's efficient beyond the wildest dreams of George Orwell.

Sure, we can take measures to prevent this. We can turn our cell phones off and spend cash. But increasingly, none of it matters.

Mark Andreesen:

A lot of people looked at Facebook and saw a Web site. None of the people close to Mark [Zuckerberg] and the company thought of Facebook as a Web site. They think of it as a data set, a feedback loop.

David Montgomery, Sari Horwitz and Marc Fisher:

How federal and local investigators sifted through that ocean of evidence ... is an object lesson in how hard it is to separate the meaningful from the noise in a world awash with information.

Rolf Dobelli:

Information is no longer a scarce commodity. But attention is. You are not that irresponsible with your money, reputation or health. Why give away your mind?

Adam C. Engst:

Our only weapon in the war against the infinite is self-control. Regardless of the specifics, if you overindulge in information, no matter how good your tools, you will eventually be crushed by the infinite.

Stefany Anne Golberg:

Never mind not seeing the forest for the trees. In this ... you cannot even see the trees for the bark.
