I honestly do not understand this metaphor at all. There are reasons why some of the algorithms are better implemented in a computer. Is there some magic that will allow me to clone myself to try multiple paths in parallel? Maybe I can speed up time so that I can climb the hills fast? As a human, I have limited time and that places a huge constraint on what is feasible. Ignoring that and trying to draw parallels to algorithmic domain seems to miss out on crucial constraints.
