I wrote lots of C++ before learning Rust, and I enjoyed it. Since learning Rust, I write no more C++. I found no place in which C++ is a better fit than Rust, and so it's my "new C++".

For example, high performance servers (voltlane.net), programming languages (https://github.com/HF-Foundation, https://github.com/lionkor/mcl-rs, and one private one), webservers (beampaint.com) and lots of other domains.

Rust is close to C++ in that it is a systems language that allows a reasonable level of zero-cost abstractions.

Writing the compiler toolchains that Rust depends on, industry standards like CUDA, SYSCL, Metal, Unreal or the VFX Reference Platform.
