Eh. Anyone who observes small children will see that they learn very slowly, but constantly. And they are extremely good at it - better than nearly all adults - at a minimum they pick up language, gross motor skills like walking, running, climbing, any number of fine motor skills, within 2-3 years. They don't work quickly, they display no haste or concern for efficiency. In fact, they're quite inefficient.
