[Romans] never made any improvements on the cavalry. And amazingly, when you read the sources, they couldn't make it because stirrups were not known in Europe. For hundreds of years, the Romans couldn't make a cavalry which proved to be extremely effective.

Chess - it's a nonmainstream game. And the irony is that when you look at Hollywood, it kept using chess as the symbol of intelligence for its heroes, for its top characters, all the time. So it's from "Casablanca" to "Harry Potter." You always have chess as a very important element to demonstrate intelligence, while in normal life people think it's just a weird intelligence - like AI.

So many dictators trying to blackmail the free world because they have no way to compete on ideas, innovation or creativity. The Cold War was two competing visions of the future. I was always anti-communist but it was an idea at least, an alternative idea. We do not have a competing vision for the future because the ideals of these dictators are in the past. They are time travellers. They need confrontation and destruction to survive. The problem is, many people in the free world are sympathetic to Vladimir Putin.

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.

The legend of the best player of chess has been destroyed.

Chess is a unique battlefield for human minds and computers - human intuition, our creativity, fantasy, our logic, versus the brute force of calculation and a very small portion of accumulated knowledge infused by other human beings. So in chess we can compare these two incompatible things and probably make projections into our future. Is there danger that the human mind will be overshadowed by the power of computers, or we can still survive?

Machines taking over jobs - it's the history of civilization. Replacing farm animals, old forms of manual labor, now taking over small, menial aspects of cognition. But there's still plenty of room for creativity, for curiosity - many things that are related to passion, like art. But also, things about human communication and challenges, massive challenges that we left behind because we didn't want to take so much risk, such as space exploration, deep ocean exploration.
