You misunderstood what I mean by "gap" here. The gap isn't that it is impossible to produce security/reliability equivalent program using C vs Rust, which you seem to be arguing. The gap is that statistically for many code written in real world for various degree of efforts, Rust code will have much less of security/reliability issues, and it will take much less effort to get to the similar quality point compared to C or C++, and that gap is NOT bridgeable by making C programmer better or by inventing better conventions and styles.
