I don't like the biology argument. It sounds as if we would care about our biology in any other respect. The whole tech industry is about extending our human capacities beyond our natural limitations, fitting low-testosterone entities (aka women) into "fast moving markets with high competiton"* for the sake of equity [and to show the rest of the world just how awesome we are] is just another obstacle we want to overcome.

*I guess this makes it sound more manly and heroic than it actually is.
