1) C++: 7+ years; Rust: 3+ years.

2) C++, my employer's choice. Their rationale: easier to hire people with experience, internal codebase is mostly C++ so tooling/people more versed.

3) Rust. For me it's just easier overall to work with. It takes me an hour or so to get my head back into Rust's standard library and idioms/quirks, but afterwards it feels much better to work with: dev. workflow, testing, expressiveness. Plus it catches programming errors for me every once in a while.

4) I wish Rust had wider adoption by the industry. It's always compared to C/C++/Java/Go and the usual argument boil down to "not enough people use it".

5) I wish C++ had better compiler error messages. I have to rely on instinct when it's not scrolling through nested template/SFINAE errors to understand what's happening. Rust tells me "here's what's wrong" 99% of the time.
