Solving problems faster or comprehending a concept similar to one you already know is not the same as “improving 10 times faster”. Most of the “improvement” is already in the past. In the same way a concert pianist doesn’t “improve 100x faster” than me if he can learn a new song in 6 minutes that takes me 10 hours to learn. In the same way Bill Gates’s savings account doesn’t “improve 1 million times faster” than mine when we both earn interest. The analogy for snowboarding might be taking an experienced snowboarder and a novice, and introducing some new type of obstacle on the slope. The experienced snowboarder will learn how to deal with it much faster than the novice.
