Vladimir Putin likes Donald Trump because he supports this view of the world, that the big guys can carve it up, sit and talk about the world, carve up the countries, shape borders. For Putin, treaties, alliances, Nato, the EU are stumbling blocks.

One lesson is to not to play desperately if your position is worse but still reasonable. Lashing out wildly in an inferior position usually only hastens defeat. Meanwhile, solid, stubborn defense can demoralize the attacker, make him lose confidence. When that happens, the tables can turn. Keep fighting, stay steady, keep morale high - and public protests are good for all of these things.

The slightest sign of stability is used by local authoritarian leaders to bargain for the sympathies of Western countries that are, for the sake of a balanced relationship, bound to turn a blind eye to obvious, blatant violations of human rights and the deconstruction of democratic institutions in these countries.

You're always going to have dangerous, disaffected people in any society, and some will be violent. Increasing prosperity and reducing inequality won't solve that completely. But having big, positive dreams and a society that makes it possible to achieve those dreams is what we must strive for.

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.

[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.

Anything that we know how we do, machines will do better. Now, the key element of this phrase is, "We know how we do it." Because we do many things without knowing exactly how we do them. So this is the area where machines are vulnerable, because it still has to learn from some kind of experience. It needs something - at least the rules of the game. You have to bring in something that will help the machine to start learning. It's like square one. If there's nothing there, if you can't explain it, that's a problem.
