I think we have very steady records of President Putin, who inherited the country with democratic values.

I'm not paranoid, but I am cautious. I don't drink tea with strangers, I don't fly Aeroflot and I avoid certain countries with close ties to Russia.

Boris Nemtsov and I began to argue after Putin's return to the presidency in 2012. In my opinion, there was no longer a realistic chance to achieve regime change through peaceful political means, or real elections. Boris, on the other hand, never lost this hope. He felt that my assessment was premature and said: "You have to live a long time to see changes in Russia." He was deprived of that opportunity.

[Vladimir] Putin is more of a poker player. In poker, unlike chess, you can effectively compensate for a very weak hand by bluffing. There are fixed rules in chess, and no one knows how the game will end. Things are currently the other way around in Putin's realm. But it won't stay that way forever.

For us to make sure that we have full lives, meaningful lives, we will have to elevate our unique human qualities. And I think we know now, we can see clearly what makes us different from machines. And that's why the future is enhanced humanity.

We have again a strange gap. We have the big scientific discoveries around the second, third century BC. Then we have an invention of the so-called Arab system, the positional system of counting with zero dated to the eighth or ninth century.

I have some security that could protect me against provocations but of course there are more terrible actions that could not be stopped by any security.
