Young men (used to) bring assertiveness and a created an atmosphere of competition.
Maybe these roles aren't so clearly divided any more. For the vast number of job positions, it doesn't matter much in terms of competence who gets the job. It matters so much more that the coworkers are comfortable and enjoy the workplace.
Men had obvious advantage in physically demanding jobs, but fewer and fewer of these remain.
I as a man, prefer to work with women. I've met some remarkable women and learned a lot from them and not only in tech.
Stereotype is just another word for "expectations based on experiences". It's not claimed to be finite absolute truth.
But, if we would assume that people keep on getting more and more productive due to corporations optimizing for productivity wouldn't we see a drop off of both women and men at the same time? I don't think we would legitimately seem the existing of displacement but actually mutual decreasing.
Numbers vary, but even as of today there are low-single-digit millions of stay at home fathers (under the liberal definition of "18+ male with children in the home who does not work") vs. about ~1m total in the late 80's. Seems like it may account for a point or two on the graphs, but not much more.

In generations past, that was done by women who were counted as not having a job (despite working longer hours than their husbands, 7 days a week). That doesn't need to be the case -- and in fact, dual-income households can create jobs: cleaners, cooks (delivery drivers etc), and childcare. In my grandma's generation, a woman's household duties also included gardening and preserving foods, and making/repairing clothes -- but those jobs have been outsourced so completely that they're now seen as quirky hobbies.
