Folks, I need a hobby. I’m a C programmer who has lost his passion for programming, it seems. I’ve decided to try to spark my passion again by going back to the basics, perhaps by creating a programming tutorial Wikibook, for modern applications.

The trouble is, I cannot decide if I should make C or Rust my programming language of choice.

I use C all the time, and have barely any experience in Rust.

Do I go with ol’ reliable and risk being outdated in a few years, or go with the new language and risk being too niche and unpopular?
