Agreed, but I was mainly focusing on the aforementioned domains in which C is the 'de facto' standard due to it's properties.
However I believe there are lots of applications written in C because that was either the 'language d'jour' back when they were written or that the author was very proficient in it, which could be rewritten in something like Go,Java,C# or even Python and similar without any perceptable loss of performance.
Looking at things where C dominates to this day and show no sign of weakening, I see operating-system level code (kernel, driver, userland<->kernel interface code), libraries for cpu intensive workloads (audio/video codecs, compression/decompression, low level game framework components etc) and of course cpu intensive applications (encoders, archivers, graphics manipulation software for 2d/3d etc), I guess I should squeeze in version control software here aswell :)
However, there exists a wide range of applications outside of these areas where I think C isn't particularly competitive these days as it's strengths are dwarfed by it's weaknesses.
That's not to say that there is anything wrong with writing such applications in C, particularly considering aspects such as proficiency and familiarity, if you know C very well and feel very comfortable programming in it then it's less likely you'd want to switch to something else for 'convenience'.
