From a work perspective, I recall reading that in the next 10 years, 6 of 10 people on a development team will be security related. [Looked for the source, can't find it, due your own diligence]. 1.8 Million security jobs vacant by 2022. https://venturebeat.com/2017/06/07/global-cybersecurity-work...

The need for very seasoned professionals who have BOTH security and heavy development/business/architecture backgrounds will be a scarce thing.
