Feeling the matter is not settled at all, Mannie orders drinks.
While they discuss the matter of Mannie's opting in or out, Prof shares his political view, which he calls "rational anarchism" (6.43). The basic idea is that a person is always responsible for himself and his actions.
Prof declares the revolution at hand, but Mannie still isn't all in, so Wyoh suggests he call Mike to analyze the situation.
While they're at it, they share the truth about Mike with Prof. Prof is a little worried, but Mannie assures him that Mike is his own man, er, computer.
Mike crunches the numbers. He decides that, given current trends, Luna will exhaust its natural resources. In nine years, cannibalism will set in and the moon will become a zombie nightmare set in space… which sounds like a pretty sweet movie, to be honest.
Not one for the taste of human flesh, though, Mannie sides with revolution.
He wants Mike to calculate the odds of success, and Mike comes back with the figure seven to one against them.
