People are starting to be very skeptical of the Facebook algorithm and all kinds of data surveillance.

We've learned our lesson with finance because they made a huge goddamn explosion that almost shut down the world. But the thing I realized is that there might never be an explosion on the scale of the financial crisis happening with big data.

The Facebook algorithm designers chose to let us see what our friends are talking about. They chose to show us, in some sense, more of the same. And that is the design decision that they could have decided differently. They could have said, "We're going to show you stuff that you've probably never seen before." I think they probably optimized their algorithm to make the most amount of money, and that probably meant showing people stuff that they already sort of agreed with, or were more likely to agree with.

There's less of a connection for a lot of people between the technical decisions we make and the ethical ramifications we are responsible for.

When people are not given an option by some secret scoring system, it's very hard to complain, so they often don't even know that they've been victimized.

I wanted to prevent people from giving them too much power. I see that as a pattern. I wanted that to come to an end as soon as possible.

The NSA buys data from private companies, so the private companies are the source of all this stuff.
