...comparing the capacity of computers to the capacity of the human brain, I've often wondered, where does our success come from? The answer is synthesis, the ability to combine creativity and calculation, art and science, into whole that is much greater than the sum of its parts.

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.

He's learned his lesson very well - threaten to take action but never act on such words.
