When Steven Pinker tells us,

Language is a complex, specialized skill, which develops in the child spontaneously, without conscious effort or formal instruction, is deployed without awareness of its underlying logic, is qualitatively the same in every individual, and is distinct from more general abilities to process information or behave intelligently. -- The Language Instinct (1994), page 18,

he is talking about development and deployment of native language during childhood. For adults, the development of language is much less spontaneous and the deployment is much less "without awareness." That is probably true for all adults: "blessed few" probably means "none."
