Bicycles of the mind are amazing for producing mental leverage. That leverage amplifies the benefit you can gain from intellectual capacity, and the result is that intellectual differences between people which once were minor become vast. Or to use another, more martial analogy, technology is a sword for your mind. In medieval combat, a small difference in strength or agility or training could mean the difference between survival (and wealth) and an early grave. Today it's the difference between life in the 1% and minimum wage.
