There are a zillion reasons that C++ is still widely used (existing software, brand new software that relies heavily on existing libraries / game engines), so it's really nice to have lots of helpful features being added to the language and the standard library.
I'm ambivalent about Rust, but its best feature compared to C++ is a universal package manager and build system. I like vcpkg well enough, but it's not Cargo, it can't be.
