We've been saying Putin is a dictator for years who doesn't care about the law.

You're always going to have dangerous, disaffected people in any society, and some will be violent. Increasing prosperity and reducing inequality won't solve that completely. But having big, positive dreams and a society that makes it possible to achieve those dreams is what we must strive for.

That machines will surpass us in intelligence is inevitable. What it means is unknowable. Will they be sentient? What will they care about in the sense that determines our human motivations? All the theorizing by the experts and non-experts makes for interesting conversations and dramatic headlines, but it's more likely we will be surprised by how our technology develops and how it is used, as we so often are.

If you're already in a fight, you want the first blow to be the last and you had better be the one to throw it.

The only game [Vladimir] Putin can play is to establish a lifelong dictatorship in the country, at first de facto and finally also de jure. In this case, [Dmitri] Medvedev is an interim figure bound to assist Putin in his plan to guarantee a smooth transition to a new term in office.

At the end of the day, it's all about money.

Attackers may sometimes regret bad moves, but it is much worse to forever regret an opportunity you allowed to pass you by.
