Innumerable conditions must be exquisitely optimized for the support of humanity and of civilization. Many of them are highly time variable. Evidence showing that a wide variety of independent conditions all reached optimality during the identical narrow epoch when human beings appeared on the cosmic and terrestrial scene testifies of supernatural design and purpose rather than mere coincidence.
Societies would _not_ be better off if everyone were like Mr Spock, all rationality and no emotion. Instead, a balance - a teaming up of the internal rivals - is optimal for brains. . . . Some balance of the emotional and rational systems is needed, and that balance may already be optimized by natural selection in human brains.
C++ is a language strongly optimized for liars and people who go by guesswork and ignorance.
