1. I had about 7 years of professional C++ experience, a few more as a hobbyist. By now, I have ~10 years of Rust.

2. I would definitely choose Rust. For better or for worse, the teams I work with tend to consider developer velocity as their highest metric. Between cargo, clippy, crates and the type system, I'm orders of magnitude more productive in Rust.

3. Same thing. My life is too short to spend it debugging memory or concurrency errors.

4. There are a number of C++ libraries that have no equivalent or good bindings in Rust yet. But if you're talking of the language, no. There are C++ features that do not have an equivalent in Rust but I don't miss them.

5. From the top of my head, affine types (e.g. after a `std::move`, the type system ensures that you can't use the value anymore), proper enums, proper pattern-matching, better concurrency operations in the standard library (which pretty much requires affine types), a linter as good as clippy, built-in support for writing new linters/gradual type systems, derive macros (that have access to the AST).
