The reason I'm so salty about your response is when the breach happened, there were tons of news reports denigrating the CISO because she had a music degree. There may be a ton of reasons she wasn't good at her job (though it's hard to say as CISO is often a "sacrificial lamb" job anyway), and I'm certainly not defending Equifax, but I take major issue with the implication that a music degree makes someone unqualified for a tech job.
First, as she was CISO, she was presumably done with college many, many years ago. Lots of people have college degrees that aren't necessarily directed to the career they end up in. More importantly, though, I've found that there is a direct correlation between highly trained musicians and great software engineers. I don't know if it's a "same part of the brain" thing or whatever, but I'm actually astounded at the sheer number of "best of the best" software engineers I've worked with that are classically trained musicians. It's to the point that when hiring I give "extra points" if you will to musicians because, it my experience at least, the correlation is so strong.
So, frankly, you can take your "she had a music degree" shade and shove it.
