I think they mean that a brilliant asshole of a different type of assholery would have been fired much sooner. The fact that she’s qualified is separate.
Ah, I see. I would say in response that we're pretty much at a subjective impasse then. The thrust of my argument is that brilliant assholes are generally well tolerated. By "asshole" I don't mean someone who got canned for a harmless joke, I'm talking about toxic aggressive egomaniacs who wield their expertise and prestige as a cudgel to demean and abuse their colleagues.
I think we're in agreement, to a degree. There are some types of asshole that the industry has agreed to not tolerate. Then they say "See? We don't tolerate any kinds of assholes! You have to partner well and communicate well with people now!" Even though they absolutely do still tolerate certain kinds of assholes, like the kind you mean, and, to a degree, people who wield popular ideas like a cudgel.
I feel like the industry has at least made big leaps forward. Went I joined (during the great recession) it felt way worse, but I've also found a great company, so maybe I'm insulated in a kind bubble.
