I think maybe the point of that article was that the workplace needs to be reformed, not that gifted women should stay home or should curb their ambition.

The best hope for making progress against today’s gender inequality probably involves some combination of legal and cultural changes, which happens to be the same combination that beat back the old sexism. We’ll have to get beyond the Mommy Wars and instead create rewarding career paths even for parents — fathers, too — who take months or years off. We’ll have to get more creative about part-time and flexible work, too.

A solution like this probably reduce the number of women who opt out entirely.
