Athena said the Centurions are limited in their programming, so they don't rise up against the human models.

It raises the question of since the metals must have made the human forms, how did the human forms come to rule over the metals.

Of course there might be a main cylon somewhere, not human form, that runs things. An "Imperious leader" of sorts. I can see them avoiding such a name but perhaps, as an homage to the original, a human form might sarcastically refer to it as "Our Imperious leader"
