If by "some of us" you mean hundreds of thousands of scientists, engineers, managers, janitors, miners that dig the raw materials, shipping specialists and all sorts of professionals and billions of consumers (that allow for large scale production to be economically feasible), yeah, I guess collectively we are "smarter" than a self sufficient guy merely waiting for the right time the seeds to plant themselves, pests just killing themselves, the crops just harvesting themselves, the produce just storing itself, the next years seeds just setting themselves aside, the meals just preparing themselves and so on.
