I'm not in favour of a regulation-free world. I align myself with Teddy Roosevelt, who broke up the trusts. Regulation is necessary, but it should be in favour of the consumer, the citizen, and freedom.

We should simply accept the fact that the way machines make decisions is different, and rather look at the result. If machines are providing results that we are looking for, you would mind how much human understanding was used in the process. And more likely we should look for the way of combining human skills and machine skills. And that, I believe, is the future role of humanity, is just to make sure it will be using this immense power of brute force of calculation for our benefit.

Barack Obama took over after Vladimir Putin's first aggression, in Georgia. In 2009, he did the reset policy because they had these stupid ideas about former president Dmitry Medvedev. They thought he would be the leader, not Putin. Everyone played this game with Medvedev as their bet, Berlin, Paris, London, the idea of smoothly transferring to something more acceptable. It was always a charade, a Putin project to solidify his power and come back after four years of nominal occupation of the office by Medvedev.

Many politicians in the West cling to the notion of a partnership with Russia. They want to include [Vladimir] Putin, make compromises and constantly negotiate new deals with him. But history has taught us that the longer we pursue appeasement and do nothing, the higher the price will be later on. Dictators don't ask "Why?" before they seize even more power. They ask: "Why not?"

A grandmaster needs to retain thousands of games in his head, for games are to him what the words of their mother tongue are to ordinary people, or notes or scores to musicians.
