I have no interest seeing the day to day of that job.
Think about a plaque on a bridge. Who does it say built the bridge? The guy who never touched a shovel after the ground breaking ceremony.
A simpler explanation is that there is a perceived need to increase the number of women in management positions.
However, if the book is any indication, Tanya is a great staff engineer, probably among the best of any gender.
This of course begs the question: could it be that discriminating against men who don't display the stereotypical behaviors is detrimental to diversity? And increasing the number of women may actually help here: they may be able to empathize with people who don't fit the traditional mold.
It’s not clear that people incapable of being assertive or direct would make naturally more effective managers.
And assuming that women drawn to management positions will be more empathetic to the neuro diverse is a gigantic reach. I have no idea why that would be the case.
It appears to be much easier to advance in one's career as a self-doubting woman than a self-doubting man. This is probably because women are expected to have a high degree of self doubt and there is no assumption that they are defective if they admit to it.
And management is absolutely more prestigious and better compensated than IC work, despite what some may claim.
