If people from that world complain about Rust, I surely wouldn't want them around a C codebase.

There's nothing wrong about memory-managed languages, if you don't need to care about memory. But being unfamiliar with memory and complaining about the thing that help you avoid shooting your foot isn't something that inspires trust.

The hardship associated with learning rust isn't going to go away if they do C instead. What's going to happen instead is that bugged code will be written, and they will learn to associate the hardship with the underlying problem: managing memory.
