Nice fairy tale. First, computing wasn't new:
A man in a room full of the first 'computers':
But seriously how about
Margaret Hamilton, who programmed flight software for the Apollo landings?
Second, you do not seem to have explained why women lost interest. I suppose that hiring and promotion discrimination, sexist behaviour and attitudes of male colleagues, and gender stereotypes have nothing to do with it...
Really? I cannot think of any. Name one (for which the decline in female interest wasn't discrimination and hostility from men). Certainly there have been lots of new techniques and fields in biology, but that field seems to be humming along recruiting women. Indeed. women now earn the majority of biology bachelor's degrees. All it takes is effort to include women in a field to break the cycle of gender stereotyping.
