The international repercussions were shattering to some extent - there is no intention to repeat operations of such kind in the future.[Viktor] Yanukovych's electoral victory clearly demonstrated that there are no pro-Russian politicians in the Ukraine, just Ukrainian politicians.

Dictatorships sometimes fall unexpectedly and quickly. And [Vladimir] Putin knows that for him, the loss of power doesn't mean a comfortable retirement, but something completely different.

In Syria, Vladimir pUTIN sees the chance to make millions of refugees and weaponise them. The US has to take a lead in defending the values of the free world.

And the new middle class should also feel the effects of what he is doing. For instance, we should ask those who wish to enter the EU whether they have visited illegally occupied Crimea in the last few months and, if the answer is "yes," deny them a visa.

It's interesting that the greatest minds of computer science, the founding fathers, like Alan Turing and Claude Shannon and Norbert Wiener, they all looked at chess as the ultimate test. So they thought, "Oh, if a machine can play chess, and beat strong players, set aside a world champion, that would be the sign of a dawn of the AI era." With all due respect, they were wrong.

Remember that the machine is there to help you, because at the end of the day, you're not playing freestyle chess, advanced chess, human-plus-machine. If you are playing against other humans, it's about winning the game. The machine will not be assisting you, unless you are cheating of course. And since the machine is not there, you have to make sure that everything you learn from the computer will not badly affect the way you play the real game.
