This argument founders against a pretty simple rebuttal. Unless you believe software development of the variety practiced at places like Facebook is so intellectually challenging that its demands outstrip molecular biology, mathematics, and indeed all of science save the fields of physics, computer science, and engineering --- despite the fact that virtually all of science now requires deep facility with computers! --- then that argument has to account for the fact that every one of those fields has much better parity between men and women than software development.

Of course we all here understand that 80% of software development as practiced commercially is not especially intellectually demanding, being as it is essentially a series of variations of transforming database rows into text markup and back again.
