As expected, the people problem is the biggest factor. Turns out getting C folks to learn Rust is a difficult proposition (hello, lkml) but the other way around it isn't too much of a problem.
I wonder how much of it is low-level experienced developers only ever using C fail to see that C is not the universally best tool (or, 'if all you have is a hammer, everything looks like a nail' question).
