A zero-day exploit is a method of hacking a system. It's sort of a vulnerability that has an exploit written for it, sort of a key and a lock that go together to a given software package. It could be an internet web server. It could be Microsoft Office. It could be Adobe Reader or it could be Facebook.

We hack everyone everywhere. We like to make a distinction between us and the others. But we are in almost every country in the world. We are not at war with these countries.

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.

If the United States is promoting the development of exploits, of vulnerabilities, of insecurity in this critical infrastructure, and we're not fixing it when we find it, instead we put it on the shelf so we can use it the next time we want to launch an attack against some foreign country. We're leaving ourselves at risk.

My whole model, from the beginning, was not to personally publish a single document. I provided these documents to journalists because I didn't want my biases to decide what's in the public interest and what is not.

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.

The Iraq war that I signed up for was launched on false premises. The American people were misled. Now, whether that was due to bad faith or simply mistakes in intelligence, I can't say for sure. But I can say it shows the problem of putting too much faith in intelligence systems without debating them in public.
