tldr I wrote in C when I needed to crunch numbers (running the cosine similarity function over and over in short succession) and then I also wrote in high level scripting languages like Ruby when I need to hit APIs and do string manipulation. Use the right tool for the job. Do not be a language ideologue.

But even so, the main (but not only) reason to learn C is as the lingua franca of programming, the imperative language that makes it easy to learn all other imperative languages.
