American ideology is based on Hegelian idealism where the only reality is ideas. Actually, quantum mechanics supports this view, at least several of its interpetations, that the world is simply ideas. Thus, the ultimate value is in ideas according to these predominant ideologies/theories.
Implementation has no value unless it involves subtsantial breakthrough in hardware/software. Facebook is a crude php application as some kid posted in a forum. No breakthrough there. Do not confuse with discoveries like the light bulb, where implementation of electric laws provided the added value. There, everyone had the idea of a light bulb but only one found the viable solution.
