Hi! Developer working in C here. I'm neither a kernel dev nor an embedded dev.

My current job is network programming on the core product of my employer. It's "legacy" in the sense that it's been around a long time but it's actively developed and continually extended to meet rapidly evolving customer needs.

I also wrote C in my previous job doing non-flight software for a space mission, analyzing telemetry, processing image data, automated planning of camera targeting, etc. Much other work was done in scripting languages, and when those weren't performant enough for the task then I wrote C libraries to do the heavy lifting for them to interface with.

You don't live in a bubble. There are whole segments of the software industry where you'll never see C developers, and there are many companies where you C could (should?) be used but isn't because it's unhip and old. Software development these days is pretty fragmented and there's a tendency for people to think that their experience describes everything, but it's not the case.
