I understand your point, but as a practical matter, we can at least, for the time being, insure that the factual matter provided to them is as correct as we currently know it to be. Deferring resolution until the day they all have properly trained minds seems to me to be the sort of thing Voltaire was referring to when he noted that "le mieux est l'ennemi du bien".
