Once I spoke about this subject among a group of English intellectuals. One of them was a professor on Roman Law at one of the leading British universities. I asked him,what was the official language of the Byzantine Empire? He said, maybe sometime in the sixth or the seventh century.The Justinian Codex, the rule of law in the Byzantine Empire which was produced by Emperor Justinian, it was written in Latin.And he looked at me ,he knew that I knew already that the only original copy was found in the beginning of the sixteenth century.

A machine helps us to annihilate our weaknesses. We don't have a steady hand. We can lose all vigilance. We can be distracted by something that is not that relevant. But we have intuition. We can feel certain things. And with a machine you can check whether it's right or wrong. That's why by bringing the two together, you create a very, very powerful combination.

Many Republicans who traditionally were for a positive role in the world, anti-Russian, now they want to defend their party and leader, and they don't care about real arguments. The paradox is the Democrats were so timid in criticising Vladimir Putin. Barack Obama appeased him and now they are criticising Putin's interference in American democracy. It is a strange reversal of the roles.

It was not about losing my mental power; it's about not feeling good about my contribution to the game.

Of course, if people do not want to do any work then it is better to start the game from a random position.

It's not enough to be talented. It's not enough to work hard and to study late into the night. You must also become intimately aware of the methods you use to reach your decisions.

I have no idea how long Putin will last. The good news is, Putin doesn't know either. It will be sudden and it won't be peaceful. He has burned his bridges.
