Since @newsgoth raised the topic, I'd like to keep it going. My intuition is that there are a LOT more GRC types of people out in the workforce than there are pen testers, SOC analysts, bug hunters, REs and so on.
I will say that the thing which really drew me in to security was risk. I read the book "Black Swan" before a lot of risk programs starting crowing about black swans, and it entertained me endlessly to watch companies try to enumerate and quantify their black swan risks/exposures.
I learned a ton about decision making under uncertainty, and, in particular, that most companies don't have an appetite to be diligent about it, and so we end up with the likelihood x impact heatmap nonsense that lets people press on with their preconceived notions about what risk priorities are.
I do think that a fundamental problem we have in IT is a lack of understanding about what can go wrong. We make what we think are informed decisions, but they generally are not. We lack imagination, which is why I think we need more red team consultations in the GRC field.
