I think an important flaw in Robert's idea, apart from the ones that have already been said, is that it lacks a mechanism. He alludes to precession, but does not explain how exactly that could affect human affairs.

Finding patterns is all fine and good, but if you don't explain how the wheels of the machine mesh into one another, your idea will remain unsatisfactory.
