As a matter of fact, that's part of the reason I want to learn C. I started learning Rust, and see a lot of potential, but ultimately find I lack the context to:

1. Appreciate the language. 2. Really understand what's happening in memory.

I hope that learning C will provide both of these things, while also gaining the benefit of learning one of the only widely used languages that I can fit in my head all at once.

Learning more programming languages will make you a better programmer irregardless as it will expose you to different programming patterns, paradigms and the limitations/improvements that result from those.

This is especially true for a popular language, no matter if the language is considered "good" or not. This allows you to understand the libraries/code you will encounter down the road.

I would only discourage one from learning a programming language which is tied to a specific commercial product (most of those just die in the same niche and thus lack the practical utility).

Good luck using Rust for PostgreSQL development, or 100.000 other projects that use C. Not everything is a greenfield project.

My goodness, what an idea. Why didn't I think of that? https://www.youtube.com/watch?v=BOEYSLlQy9s
