I think you missed the point. Alex Honnold didn't woke up one day morning and decided to climb El Cap in the afternoon. He has been preparing for the climb for almost 7 years. He memorized each and every step he would make during the climb. He even abandoned his first solo attempt because the conditions didn't seem to be right. It was never a do or die situation. He wore the same set of clothes throughout the practice sessions and the climb. Everything was done to minimize the risk. For me Alex Honnold's solo is an example of what a Human can achieve with the right amount of practice and preparation.

It’s dumb as rocks, agreed.

But it’s the massive prep they do and skills they have that make it genius
