The author of the post mentions having listened to an interesting podcast on OT (Operational Technology) cybersecurity compared to IT (Information Technology) cybersecurity. They note that there are thousands of vacant positions in OT cybersecurity, which is less known than IT cybersecurity, and wonder if this means it is less competitive and better paid. The author also questions the differences between these two fields in the context of infrastructure as code and Kubernetes.
