I used C in the late 80s and 90s because it was the only viable option for many use cases. In the late 90s I got heavily involved in Java, and C usage dropped. Had some spikes of C++ work (which I despised), and then working in many different languages with no real work on C or C++ in at least 18 years or so.

What always killed me the most in C was the absolutely anemic standard library. OS’ had more libraries, but still very low level stuff.
