It would be one thing if he were just incredibly bold and daring and were getting away with it; instead, its clear that his method is a very slow, methodical process in which he manages to practically guarantee that he will have a safe and effortless climb. Even in the interviews after this, it is clear that he is committed to his routine and managed to set-up this climb in such a way that it simply represented a comfortable, natural step in his evolution as a climber. He talks about it almost matter-of-factly.
Truly awe-inspiring.
