When you think about the abolition of slavery for example, for the ruling class with the rich white people owning plantations and states, and things like that, slavery was to their benefit. To oppose it didn't make any sense at all on a rational basis. But on a rights basis, on a principle basis, it made obvious, overwhelming sense.

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.

Initially I was very encouraged. Unfortunately, the mainstream media now seems far more interested in what I said when I was 17 or what my girlfriend looks like rather than, say, the largest program of suspicionless surveillance in human history.

You would be surprised how effective, at least for influencing low-information voters, negative propaganda about me is.

One of the reasons that I came forward and sort burned of my life to the ground, and I can't go back and see my family in the United States - I obviously lost my job, which I was quite comfortable with. I lost my home. It was because I felt there was no alternative.

I've talked to a lot of pretty good lawyers around the world. I'm non-extraditable. That's the real reason the US government was pissed off, even when I was initially in Hong Kong.

Someone responding to the story said 'real spies do not speak like that'. Well, I am a spy and that is how they talk. Whenever we had a debate in the office on how to handle crimes, they do not defend due process - they defend decisive action. They say it is better to kick someone out of a plane than let these people have a day in court. It is an authoritarian mindset in general.
