I'm sincerely curious what lead you to leave this comment.

Is there really any mystery to why someone would prefer a language they know and are comfortable with. I'm more concerned why that seemed provocative enough to require inquiry. Rust is a very interesting language for sure, but there's an extremely robust c ecosystem that one would lose by transitioning at this point. And for library creators, there's much more to lose.

I felt this comment was incongruous, like it was a response to a question no one asked. I wanted to understand this better. I didn't interpret it as provocation. You seem to be reading a criticism of the C ecosystem into my question, as if everyone should drop C and learn Rust, but that is not what I meant nor what I believe.

Looks like the person prefers C, and is comfortable with it. I am curious about why you are curious?

Being comfortable with C is just fine, but doesn't satisfy me as an explanation. Eg, if I try to put myself in their shoes, being comfortable with C doesn't lead me to post this comment.

I saw something I didn't understand and wanted to understand better. Not much more to it.
