The inventor’s real genius was not to build a chess-playing machine. It was to be the first to notice that, in the modern world, there is more mastery available than you might think; that exceptional talent is usually available, and will often work cheap.
And there lies what I think of now as the asymmetry of mastery – the mystery of mastery, a truth that is for some reason extremely hard for us to grasp. We over-rate masters and under-rate mastery. That simplest solution was the hardest, partly because they underestimated the space inside the cabinet, but also because they overestimated just how good the chess player had to be.
