Agreed! I've always thought that it's an innate-ish lack of affinity towards machines that's partially responsible. Human infant females show a toy bias away from toys modeling machines, and even female baby primates of other species prefer soft toys (interestingly, the infant male rhesus monkeys show no preference between the "boy" and "girl" toys; but the females actually show a preference away from trucks and other mechanical toys.) You need to both have an affinity for machines and mathematical thinking.
