I'm genuinely surprised there are Rust developers out there that don't know C. Perhaps I'm showing my age, or my ignorance to how much CS education (even self-taught) has changed.

It's still thought but it's mostly a pointer course from my recent experience. It's a low credit subject where you play around with arrays and strings, maybe there will be an overflow calculation as well. Whereas something like Rust you'd do in a high credit course project where you have freedom over the tech stack and actually produce something with functionality. Edit: My point with the replacement is not that juniors don't/won't have C on their CV but that a manager would be more willing to replace an experienced dev with 1 year exp in the current tool with 2 worse devs also with 1 year exp in the current tool compared to replacing an experienced dev with say 10 years of experience in the current tool with 2 worse devs with 1 year experience in the current tool.

  I understood (and agree) with your original point. My comment about not having C experience/knowledge came from the article, where it really did sound like just that.

I studied physics, not CS, so I can't really speak to the CS curriculum part. But I am someone who has written rust professionally for a few years so I'll describe how I got there. I think the most experience I've ever had with C was writing a fourth order Runge-Kutta routine and calling it from python for a college project. Maybe 20 lines of C? In industry for the first 5yr I wrote lots of python and java code for web APIs and "big data" systems. Simultaneously around 2015 I started getting interested in rust because it seemed interesting, and like it would probably play a big role in the next 20yr--memory safety without a garbage collector is inherently compelling if you've spent time trying to make java GC act right. Eventually I got a job which was a full time rust gig. After about 3 years of that I ended up in a golang shop. So I've written some tens of thousands of lines of rust and only a few lines of C. I read C, but it would take a while for me to get comfortable writing it. But I wouldn't, probably, because I can use rust instead.
