I write code that interfaces with hardware (health care imaging systems), processes images, and a little computer vision here and there. Very few service calls in that stack.

I jump up 1000 levels of abstraction from time to time, and when I do, I agree that security is extremely important (FDA class III device and HIPAA compliance is mandatory.) I'm also a lead, so I have to know enough to call BS when I hear it from a team member.
