Since the article provided their personal theory, I will provide mine. I do not think its the work activity itself that matter, but that a person who picks between multiple choices of potential future professions, the deciding factor when everything else has been considered is the amount of people with similar life experience that one is likely to find. If you are a young parent, you have a minor preference for places which employ a lot of other young parents of the same gender. When everything else is equal, such preference can have a huge impact on gender statistics.
Seems like the author did a lot of research then just jumped to conjecture for his conclusion.
> Today's programming resembles design and construction of large mechanisms a lot more than word processing. The majority of women just don't find these things as interesting as men do.
Do the majority of men find those things interesting? Do women like word processing and menial tasks?
Is it possible that as the job of software engineer garnered more money and status, women were shut out?
I don't know, but this article doesn't answer these questions.
On an additional note, I find it odd that software always gets so much focus: for example, 99 percent of construction jobs are held by males in many countries (and a large portion of these jobs do not involve heavy physical labor, if that is a concern - i.e. heavy machinery operators, foremen (forewomen?) etc ).

See link above. I think we might be asking the wrong question, focusing on too narrow of a field. The better question might be, why do certain fields get dominated by women, and certain fields are devoid of them? I think there is a much broader hypothesis here to be tackled then one concerning a single field.
A more interesting study to me would be why so many "programers" seem to exhibit traits commonly associated with OCD or Asperger syndrome(some times both). Wired even called it "Geek syndrome" http://www.wired.com/2001/12/aspergers/
Burn the heretic!
