Take the amount of time that it takes to become comfortable in a given language, and now increase that by an order of magnitude: this is how long it will take you to become comfortable writing C++ unsupervised. The language simply has too many subtle footguns to allow a beginner to be unleashed on a codebase (compare Java, where the worst a beginner will do is write a tangled mess of inflexible classes, but it will still largely work). The massive quantities of pre-C++11 documentation out there aren't doing the language any good either. And colleges (with the exception of game development programs) aren't teaching C++ anymore (and where they are, they're teaching C++98/03), so writing anything new in C++ means you're either going to maintain this yourself in perpetuity (talk about job security), or you're going to commit to a long period of coaching a beginner on the language, or you're going to hire an experienced C++ programmer for a significant multiple of what a less specialized programmer would have cost you. So in the context of a conversation about the costs of training and long-term maintainability, well, you should probably write all your stuff in Java, but if you can't, then you're better off selecting Rust over C++. I can teach Rust to anyone that knows Python, and once you know Rust you're at least familiar with the most useful subset of C++. |

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.
