While the US Constitution marks these programs as illegal, my government argues that secret court rulings, which the world is not permitted to see, somehow legitimize an illegal affair. These rulings simply corrupt the most basic notion of justice - that it must be seen to be done. The immoral cannot be made moral through the use of secret law.

The question that we, as a society, have to ask is, are our collective rights worth a small relative advantage in our ability to spy on other countries and foreign citizens? I have my opinion about that, but we all collectively have to come to our opinion about it.

As a technologist, I see the trends, and I see that automation inevitably is going to mean fewer and fewer jobs. And if we do not find a way to provide a basic income for people who have no work, or no meaningful work, we’re going to have social unrest that could get people killed. When we have increasing production - year after year after year - some of that needs to be reinvested in society.

From the very beginning, I said there are two tracks of reform: there's the political and the technical. I don't believe the political will be successful, for exactly the reasons you underlined. The issue is too abstract for average people, who have too many things going on in their lives.

There is a policy response that needs to occur. There is also a technical response that needs to occur. It is the development community that can really craft the solutions and make sure we are safe.

I believe that when [senator Ron] Wyden and [senator Mark] Udall asked about the scale of this, they [the NSA] said it did not have the tools to provide an answer. We do have the tools and I have maps showing where people have been scrutinised most. We collect more digital communications from America than we do from the Russians.

When I talk about the polling, I'm talking about the principles. It shows these officials are knowingly attempting to shift public opinion, even though they know what they say is not factual.
