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.

Many people think they are too refined, or too rational, to entertain a real sense of wonder in themselves or in others. This is preposterous to me, since the natural world is full of endless wonders, both on Earth and especially in space, no matter how you think it was created.

Putin recognized that if he could get enough money, everything would be under control.

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.

The regime is in trouble economically and can no longer offer anything to its citizens. That's why [Vladimir] Putin has to pursue an aggressive foreign policy, so he can serve his people the fairy tale of Russian pride and regaining its strength as a major power.

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.

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.
