One journalist said that everybody in Russia is miserable. Russia is a terrible place. And I'm going to end up miserable and I'm going to be a drunk and I'm never going to do anything. I don't drink.

We can plant bugs in machines. Once you go on the network, I can identify your machine. You will never be safe whatever protections you put in place.
