[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.

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.

Without a goal [maneuvering is] aimless. You might be a master tactician, but you'll have no sense of strategy.

Many so-called pragmatists want nothing to do with space exploration or other kinds of ambitious endeavours that don't have a clear payoff. This mentality is hugely damaging to our success as a civilization. Our desire to understand the universe is kindled by curiosity and wonder, and this has fuelled countless scientific breakthroughs.

Furthermore, the situation in the North Caucasus is rather unstable. Mutual relations and the cooperation between [Vladimir] Putin and [Ramzan] Kadyrov, the high price that has been paid to buy the loyalty of the local elite through an enormous tribute of multibillion[-ruble] investments, all this cannot be an arrangement for good.

I believe more than ever, machines will put new challenges, and that means we'll have to be more creative and more human, because that's the way to make the difference.

Ratings are king and the money keeps flowing, and partisanship is so strong today that people rely on a few sources absolutely instead of thinking critically. So even being a cheerleader for a gameshow-host president with no respect for the rule of law or America's reputation in the world may not be a career-ending move.
