There are plenty of C++ programmers to hire from. I know because we are hiring both at experienced and junior levels. Furthermore, a C++ programmer is not significantly more expensive than other programmers according to SO salary surveys. An experienced programmer will demand a good salary no matter which language he uses.

I gather from this post that you seem to use a risky strategy for your development - let juniors loose on a problem and hope that Rust/Java will save them. Or is that just a straw man? In any case, all juniors should get coaching, CI with static analysis and code reviews are likewise highly recommended.

Finally, I can't understand how someone can recommend Rust over C++ for long-term maintainability with a straight face.

The first stable version of Rust was announced four months ago, let's talk again in 10 years and see how your code from 2015 is doing.
