Elizabeth Buchanan, the director of the Center for Applied Ethics at the University of Wisconsin-Stout:

But just because we can do this with the data, should we?

Douglas Bonderud:

When it's all said and done, there's no such thing as a "free" app -- and the real cost is measured in data, not dollars.

danah boyd:

We are collectively architecting the technological infrastructure of this world. Are we OK with what we're doing and how it will affect the society around us?

Dan Geer:

A right to be forgotten is the only check on the tidal wave of observability that a ubiquitous sensor fabric is birthing now, observability that changes the very quality of what "in public" means.

Zeynep Tufekci:

Algorithms are meant to be gamed.

An algorithm can perhaps surface guaranteed content, but it cannot surface unexpected, diverse and sometimes weird content exactly because of how algorithms work: they know what they already know.

Casey Newton:

There is the inescapable sense that when it comes to your data, disaster is always one step ahead of you.

Chris Soghoian:

Effective privacy education should not be communicated with a nudge and a wink.

Ed Felten:

Storing data on a phone carries an inherent risk. The complexity of the software on our phones, and the network and cloud infrastructure to which they connect, makes it difficult to identify, let alone secure, all of the points of vulnerability. It's prudent to assume that anything on your phone is potentially at risk.
