> With C you may, if you wish, develop a big sensibility to race conditions, and stay alert. In general it is possible that C programmers have their "bugs antenna" a bit more developed than other folks.

I think there are effects in both directions here. In C you get burned, and the pain is memorable. In Rust you get forced into safe patterns immediately. I could believe that someone who has done only Rust might be missing that "healthy paranoia". But for teaching in general, it's hard to beat frequent and immediate feedback. Anecdotally it's common for experienced C programmers to learn about some of the rules only late in their careers, maybe because they didn't happen to get burned by a particular rule earlier.

> Rust may create a false sense of security, and in the unsafe sections the programmer sometimes, when reviewing the code, is falsely convinced by the mandatory SAFETY comment.

This is an interesting contrast to the previous case. If you write a lot of unsafe Rust, you will eventually get burned. If you're lucky, it'll be a Miri failure. I think this makes folks who work with unsafe Rust extremely paranoid. It's also easier to sustain an that level of paranoia with Rust, because you hopefully only have to consider small bits of unsafe code in isolation, and not thousands of lines of application logic manipulating raw pointers or whatever.

The amount of paranoia I need for unsafe Rust is orders of magnitudes higher than C. Keeping track of the many things that can implicity drop values and/or free memory, and figuring out if im handling raw pointers and reference conversions in a way that doesn't accidentally alias is painful. The C rules are fewer and simpler, and are also well known, and are aleviated and documented by guidelines like MISRA. Unsafe Rust has more rules, which seem underspecified and underdocumented, and also unstable. Known unknowns are preferable over unknown unknowns.
