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.

I hope you have read the election programme of the Labour Party...this is not socialism. It is Bolshevism run mad.

I don't think there's anything, any threat out there today that anyone can point to, that justifies placing an entire population under mass surveillance.

Custom developed digital weapons, cyber weapons nowadays typically chain together a number of zero-day exploits that are targeted against the specific site, the specific target that they want to hit. But it depends, this level of sophistication, on the budget and the quality of the actor who's instigating the attack. If it's a country that's less poor or less sophisticated, it'll be a less sophisticated attack.

Anyway, it's not true that the authorities cannot access the content of the phone even if there is no back door. When I was at the NSA, we did this every single day, even on Sundays. I believe that encryption is a civic responsibility, a civic duty.

There are programs such as the NSA paying RSA $10 million to use an insecure encryption standard by default in their products. That's making us more vulnerable not just to the snooping of our domestic agencies, but also foreign agencies.

Hong Kong has a reputation for freedom in spite of the People's Republic of China. It has a strong tradition of free speech.
