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.

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.

It was an impressive achievement, of course, and a human achievement by the members of the IBM team, but Deep Blue was only intelligent the way your programmable alarm clock is intelligent. Not that losing to a $10 million alarm clock made me feel any better.

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.

I can't think of a scenario under which [Vladimir Putin] would gradually resign from power. For him and those around him, power became a source of unlimited enrichment. A loss of power would be tantamount to an annihilation of the economic success that has been achieved so far.
