I truly believe that's the only reason people aren't using Rust as a replacement for C / C++ immediately. The adoption isn't widespread, but I'm rather optimistic it will be.
It's getting there.
It's getting there.
My C programmer friends like the dangerous features of the language and want to use them. Their programs are designed around the assumption that they can mutate anything in memory whenever they want to. They use mutable global variables. They would strongly dislike Rust's memory protections and ownership concept, and its other safety features.
