It was initially thought that programming was like sewing, and the "real" work was in the hardware.

Then it was realized that programming was very real and significant work, and the men in charge took over those responsibilities.

I think all we can conclude is that there's no reason women can't be just as successful at a career in programming as men, aside from social pressures. A statement which probably applies in both directions to nearly all fields.

(Not that you were necessarily arguing otherwise, but for the benefit of those less familiar with that history.)
