One of my optimistic prophecies is based on the assumption that machines could have the best algorithms in the universe, but it will never have purpose. And the problem for us to explain purpose to a machine is because we don't know what our purpose is. We have the purpose, but we still ... When we look at this global picture, a universal picture, to understand what is our purpose being here on this planet? We don't know.

You cannot say, 'Go! Go! Rah! Rah! Good move!' People want some emotion. Chess is an art and not a spectator sport.

We know that for the last 300 or 400 years, the size of human bodies is growing. Now what happened is that we suddenly, in history, have the backward process. We have these great Greek athletes, we have ultra-powerful Roman soldiers. You look at the size of the Roman soldier who has to carry all this ammunition. You're talking about 300,000 Arnold Schwartzeneggers.

This is the essential element that cannot be measured by any analysis or device, and I believe it's at the heart of success in all things: the power of intuition and the ability to harness and use it like a master.

Losing can persuade you to change what doesn't need to be changed, and winning can convince you everything is fine even if you are on the brink of disaster.

I would not draw definitive conclusions from that. If we look at South and North Korea, it is pretty hard to believe that we're dealing with the same people. Half of the people are forced to live in a concentration camp; the other have created one of the most dynamic economies in the world.

A very strong player can manage and can just know how to manage a thousand positions. I get it; it's a very arbitrary number. So then you have the world champion who could do more. But, again, any increase in numbers creates, sort of, a new level of playing. And then you go to the very top, and the difference is so minimal, but it does exist. So even a few players who never became world champion, like Vassily Ivanchuk, for instance, I think they belong to the same category.
