I think I come down somewhere close to this. Idiomatic safe Rust is noticeably slower and less scalable than the usual high-performance systems code many C++ developers write. This puts them in the position of either abandoning performance they know is possible or abandoning Rust code that is safe and sane, neither of which feels good. Anecdotally, all of the happy productive Rust programmers I know do not come from a hardcore systems background. They were mostly Java and Python developers that wanted to get a bit closer to the metal. For them it is probably a great experience, and the performance is an improvement relative to what they are accustomed to. There are quite a few shops that use Rust and C++ together, often wrapping a C++ core (for performance) with a Rust API layer (for safety).
